Best Mattresses to Buy Online in 2021

You have great options to find the best mattresses to buy online.

Whether you’re looking for a smart mattress, a mattress that will alleviate joint pain, or the most comfortable mattress you’ve ever slept on, we’re here to help. We’ve put together a buying guide to compare the best mattresses and help you know what to look for in your mattress purchases.

Best Rated Mattress: Saatva

A Saatva mattress is built for comfort and luxury while costing a fraction of what you would pay at a traditional mattress retailer. Our Saatva mattress review will help you know if this is the right mattress choice for your needs.
Overview of the Saatva Mattress Saatva

Saatva mattress reviews have a lot of positive things to say about this amazing mattress, and our review is no exception. The Saatva mattress is unique in the online mattress category as it has a coil-on-coil construction, while most online retailers offer only foam or hybrid options. Saatva’s lower coil unit provides the support base, and the top coil system features comfort coils. The comfort coils are individually wrapped, which allows them to contour and respond to your body.

Similar to a foam mattress, this coil-on-coil system eliminates most motion transfer. That makes this bed perfect for couples, especially if one half of the couple tends to toss and turn. Atop the coil system is a Euro pillowtop for additional comfort.

For all of these reasons and more, Saatva is our top choice for Best Overall Mattress & Best Luxury Mattress.
Pros Saatva

After our Saatva mattress review, we’ve ranked Saatva as the Best Overall Mattress. Here are some of the reasons we fell in love with this mattress.

15-year warranty: Saatva offers a 15-year warranty on its mattresses. If your mattress is deemed defective within the first two years of your ownership, Saatva will replace it at no cost to you. After two years, the policy changes a bit. For the next 3-15 years, the company will recover or repair your mattress but not fully replace it.
120-day sleep trial: Saatva gives you approximately four months to decide whether or not you want to keep your mattress. Should you realize on day 119 that you don’t love your Saatva mattress in spite of the positive Saatva mattress reviews, the company will come and pick it up and refund you in full.
Adjustable base: Saatva now offers the Lineal Base, an adjustable base that allows you to move your mattress up, down or flat. This is something that many Saatva mattress reviews rave about, and we’re no exception.
Cooling materials: Are you a hot sleeper? Do you often wake up sweating? If so, Saatva could be the perfect mattress for you. Coil-on-coil and hybrid mattresses are cooler than their foam counterparts.
Easy rotating: Due to Saatva’s construction, the mattresses do not need to be flipped. They do, however, need to be rotated at least once a year. While the mattress is heavy, the 14.5″ model comes with handles that make the rotation a breeze.
Eco-friendly materials:  Saatva mattresses are comprised of 100 percent eco-responsible materials. You can sleep soundly knowing the company is doing its part to reduce waste.
Free white glove delivery and mattress removal: Don’t want to unpackage or set up your mattress yourself? Saatva will do it for you! Simply select the optional white glove delivery and the company will take care of the setup. Plus, if you want to get rid of your old mattress, the company will take it away for you.
No motion transfer: Saatva’s coil-on-coil construction helps eliminate motion transfer. If you have a partner who tends to move around in their sleep, Saatva will help ensure your side of the bed stays firm and unmoved.
Varying degrees of firmness: The majority of online mattress companies we reviewed only offer one level of firmness for its mattresses. Saatva differentiates itself by offering three, which many Saatva mattress reviews emphasize as being a major help in finding the perfect firmness.

Cons Saatva

Delivery time: Saatva mattresses are made to order, which means they can take a bit longer to arrive than competitors. Delivery time varies depending on your location but typically takes between five and twenty days. If you’re needing a new mattress immediately, you might not want to wait such a long period of time.
Heavy: Mattresses aren’t light, but Saatva is particularly heavy. A queen-sized Saatva mattress weighs nearly 120 pounds! Thus, if you find yourself redecorating or moving often, you may be deterred by Saatva’s weight.
Less-competitive warranties: Trial and warranty are shorter than some competitors.

Product Features Saatva

The Saatva mattress is engineered for comfort and perfect for couples who share a bed.
Strong Coils
The magic of this mattress starts with the coils. Saavta is made from individually wrapped coils in the top portion of the mattress contour to the shape of your body. Also, a tempered steel support lower coil base helps to prevent sagging issues you might see in other mattresses.
Comfortable Foam
The foam in the mattress makes a big difference. The mattress also has a foam encased, anti-sag edge support to ensure better durability and more sleep surface. High-quality memory foam reduces pressure and tension on the lower back, providing optimal lumbar support.
Euro Pillowtop
The top layer is all about comfort. The Euro pillowtop offers more cushioning than most regular pillowtop mattresses. This layer also has a special fabric called Guardin. It helps prevent bacteria and keeps the organic cotton clean for longer. You’ll still need to clean your mattress, but the antibacterial materials in the bed will help you know you’re in a clean bed.

The Saatva Plus Soft Mattress is the softest of Saatva’s offerings and geared for those who like to feel their mattress hug them. This mattress is perfect for side sleepers or those who have trouble with their arms falling asleep.

Best Overall Foam Mattress: Nectar

Nectar

In our opinion, Nectar offers the best foam mattress you can buy online.  Founded in 2014, the company describes its mattresses as “designed for better sleep.”  Nectar’s mattresses have four layers of foam, each designed to suit a different need. In addition, nectar provides plush yet firm support and keeps you cool throughout the night.  This makes Nectar a top choice as best mattresses to buy online.

Nectar Pros

365-day sleep trial: Nectar allows you one full year to make up your mind about whether to keep or return your mattress.  This is the best mattresses Sleep trial.
Everlong Warranty: Nectar has an Everlong Warranty that guarantees the quality, materials, construction, and durability of your mattress.
Free shipping and returns: When you buy a mattress from Nectar, it ships free (as long as it is not going to Hawaii or Alaska). If you decide to return your Nectar mattress, you can do so free of charge.
Perfect for hot sleepers: Nectar mattresses have a medical-grade cooling system to help you avoid getting too hot at night.
Support: Nectar provides plush yet firm support.
White-Glove service: Nectar provides an optional white-glove service for removing your old existing mattress.

Nectar Cons

Cooling system: Nectar has an excellent cooling system. However, foam mattresses are not as cool as hybrid mattresses. If you sleep hot, you may want to check out a hybrid or coil-on-coil mattress.
Limited free shipping: Nectar provides free shipping to 48 states.  Unfortunately, Hawaii and Alaska are not included.
One Level of Firmness: Nectar does not allow you to customize the firmness. Thus, if you are very particular about wanting either a super-soft or super-firm mattress, Nectar may not be the best mattresses to buy online for you.

Best Overall Customer Reviews: Casper

Casper responds to feedback so quickly that reviews made from less than a year ago are already outdated. For example, in 2018, reviewers commented on the lack of variety when it came to firmness options. So, Casper rolled out two new Casper mattresses that spanned from firm to medium-soft. With this type of growth and understanding of their market, it’s no wonder why Casper has earned the trust of thousands of sleepers, becoming one of the highest-rated beds in the competition.

Top 5 Reasons Why More Sleep Means Less Stress

Casper Pros:

Three mattress and firmness options
100-night in-home trial
10-year limited warranty
Helpful customer service available 7 days a week
Eco-friendly manufacturing

Cons:

Higher price than some competitors (for Casper and Wave models)

The Layers of a Casper Mattress
Casper has introduced three models to their line-up, two of which include hybrid or all-foam options. This gives buyers all the flexibility to choose the perfect mattress for their sleeping style, preference, and budget.

The Cost of a Casper Mattress
In comparison to the cheap college mattress that you found in your friend’s basement, a Casper mattress will be quite a bit more expensive. However, the cost is matched in quality. The sliding scale of costs between The Essential and The Wave gives you the liberty to decide what amount you want to budget for with your new bed. With financing available for any of Casper’s mattresses, you should start budgeting for the cost of good, healthy sleep.

Which Type of Sleeper is Casper Best For?
From The Essential all the way to the hybrid version of The Wave, you really can find a Casper mattress for any type of sleeper. If you’re looking for a firmer option, you’ll find that The Essential might do the trick for you. While The Wave and The Casper are both considered medium to medium-soft, the innerspring coils of both the hybrid Wave and Casper offer another substantial layer of support.

Side Sleepers: You’ll enjoy the spinal alignment of the gel pods in The Wave as well as the Zoned Support in The Casper. The hybrid versions of both of these will give you added support if your body type is heavier. Lightweight body types might find that the all-foam mattresses allow them to sink into the mattress more for that “in the bed” feel.

Back Sleepers: Targeted support in both the gel pods and the Zoned Support of The Wave and The Casper will offer relief if you typically experience more back pain. With the endorsement of the American Chiropractic Association, The Wave will be the most in line for someone wanting better spinal alignment in their mattress. For anyone looking at their cost-effective solutions, the firmer composition of The Essential might be what you’re looking for if you want an all-foam bed that you sleep “on” rather than sleeping “in.”

Stomach Sleepers: Zoned Support in The Casper will give stomach sleepers a unique support system. Rather than implement a wholly firm or soft foam layer, Zoned Support will give stomach sleepers a more comfortable feel.
Cooler Sleeping
Some people sleep cool, others sleep hot. All-foam mattresses notoriously trap heat without any way to ventilate and move air away from sleepers, but Casper targets this with perforated foam layers to help keep sleepers cool. These breathable layers, as well as a heat-wicking, wool-infused cover in The Wave, help the all-foam mattresses stay cooler than its competitors. If you tend to sleep especially warm and are really looking for a mattress that cools you off, the Hybrid version of The Wave will be your best option. With innerspring coils, the mattress is more ventilated, so hot air can move away from the sleeper and keep air circulating beneath you.

Free shipping: Leesa mattresses ship for free (and return for free) anywhere in the U.S. and Canada.
Generous warranty: Leesa offers a 10-year warranty on its mattresses. Within the first ten years of owning your Leesa mattress, the company will repair or replace your mattress free of charge.

Leesa Mattress Cons Leesa

Because Leesa won’t be ideal for everyone, here are some things to consider:

Firmness level: Like most mattress companies, Leesa only offers one firmness level. While most people are okay with this firmness level, you should look elsewhere if you like firmer or softer beds.
White-glove delivery cost: While some online mattress companies offer free white-glove delivery, Leesa does not. Additionally, delivery is not available everywhere. We recommend contacting Leesa to find out about your options.

The Studio by Leesa Mattress Leesa

The Studio by Leesa mattress is Leesa’s new, more affordable offering and has quickly become the company’s most popular mattress.

It is a ten-inch, three-layer foam mattress that offers uniform pressure relief, body contouring, and minimal motion transfer.

The layers are the following:

Layer one: This is the comfort level made of two inches of LSA200 foam. It is the cooling layer that hugs your body and prevents you from overheating in your sleep.
Layer two: This is called the recovery layer. It has two inches of memory foam. The goal is to relieve pressure and further contour to your body.
Layer three: The third, base layer is the thickest. It is the support layer and is six inches of dense core foam that supports your body and the layers above.

Studio by Leesa Mattress Review Conclusion Leesa

After our Studio by Leesa mattress review, we feel that this is an excellent option for many people.

If you are wary of purchasing a mattress online without testing it in person, Leesa is an ideal choice. However, if you want a company that will come and set up in the mattress for you and remove your old one, you’ll need to contact Leesa first to ensure this is a service they provide in your area.

Overall, Leesa mattresses are high-quality and comfortable mattresses. They are similar to other foam and hybrid mattresses on our list in terms of comfort and quality and have similar warranties and sleep trials as well. In addition to its West Elm partnership, Leesa differentiates itself with its charitable partnerships.

Thus, if you are looking for an American-made, feel-good mattress company that offers high-quality mattresses backed by strong warranties, we highly recommend Leesa.

How to Determine the Best Mattress for a Good Night’s SleepWavebreak Media / Shutterstock

Buying a new mattress can be daunting. Not only are there hundreds of options in brick-and-mortar stores and online), but they’re expensive. You’ll want to invest wisely.

When searching for a new mattress, there are a few key things to pay attention to. Use our buying guide to help you find the right option for your needs.
Durability
If you’re investing in a mattress, you want it to last.

How long a mattress lasts depends on a variety of factors such as the type of mattress and the person using it.

Here are some standards of how long a mattress will last:

Latex mattresses: Up to 15 years
Memory foam mattresses: About 10 years
Innerspring mattresses: Around 8 years
Hybrid mattresses: Around 6 years

Of course, these are all averages. The better care you take of your mattress, the longer it will last.

Read more: Mattress Truth: How Long Does a Mattress Last?.
Mattress Size
If you’re looking for a new mattress, you probably already know what size you want. Check our FAQ section below for the standard mattress sizes.

Once you pick the size, what’s left is to pick a company that offers what you prefer.

While most mattress companies carry everything from a twin to a California king, this isn’t the case for all. If you are searching for an obscure size, you can eliminate companies that do not carry what you want.
Motion Isolation
If you sleep with a partner, you’ll likely want a mattress that excels in motion isolation. When your partner tosses and turns, you won’t feel it.

Memory foam tends to be the best type of mattress for preventing motion isolation. Next up are hybrid mattresses, thanks to their memory foam toppers.
Thickness
Mattresses come in varying degrees of thickness and most range between 10 to 14 inches.

If you enjoy sleeping low to the ground, you can find mattresses as low as five inches. In addition, you can find mattresses as thick as 20 inches! Higher sleepers, you can also add a box spring.

If this is an important factor, you can rule out brands that are either too high are too low.
Support
The first thing you should think about when researching mattresses is support.

Do you prefer to sink into a soft, plush mattress? Or, does the idea of a soft mattress make your back hurt?

If you don’t know what type of firmness you prefer, we recommend going into a store and testing out a few mattresses.

Test the mattresses by lying on your back, stomach, and side to see which mattress firmness feels best. Once you have an idea of what you like, you can begin your search.

If you have joint pain or a bad back, we recommend a firmer mattress.
Types of Mattresses
Not all mattresses are created equal. There are a few types of mattresses you can choose from:

Air mattress: We hope you don’t have an air mattress (also known as a blow-up mattress) as your fulltime mattress. Air mattresses are portable, air-filled options that are best for visitors or last-minute sleeping needs because they are not the most comfortable.
Foam mattress: A foam mattress, otherwise known as a memory foam mattress, has dense foam that contours to your body. This material is ideal for people with joint pain or back pain. The downside is that they tend to be hot and are more expensive than other types of mattresses.
Hybrid mattress: Hybrid mattresses combine the best of both mattress worlds. They feature coil-on-coil support like an innerspring mattress but are topped with memory foam for added comfort.
Innerspring mattress: An innerspring mattress is what you think of when you think of traditional mattresses. They have been around since the 1930s and feature coil support within the mattress. Innerspring mattresses are ideal for stomach and side sleepers and are typically the most affordable type.

Warranty
Mattresses aren’t meant to last forever, but good mattresses should last at least ten years.

When researching mattress companies, check out the warranty. Some companies offer a lifetime satisfaction policy, while others offer a 5-10 year warranty.
How to Find the Best Mattress DealsUnsplash

Mattress prices aren’t firm. They fluctuate depending on the time of year you purchase a mattress, but hidden discounts exist.

If you’re looking to find the best mattresses to buy online, we recommend using the following tips.
Ask About Discounts
The best way to save money on a mattress is by simply asking the retailer if they offer any special discounts.

Some mattress companies offer discounts such as:

Military discounts
Senior discounts
Student discounts

Discount information isn’t always readily available, so ask before you decide on a purchase.
Be Aware of Hidden Fees
When comparing prices, factor in extra fees.

Ask the retailer to tell you about all the possible fees before you decide on which mattress you want.
Check Delivery Fees
When looking for a new mattress, don’t forget to check out delivery fees.

Most companies offer free shipping or delivery. If you find a company that doesn’t provide this service, factor these costs into the final price of your mattress.
Get a Prescription
Not all states tax health-related products. If you have a bad back or joint pain that a new mattress could help, talk to your doctor. You may be able to have him write you a prescription for a new mattress.

Additionally, you might have a flexible spending account (FSA), health savings account (HSA), or a health reimbursement arrangement (HRA). If so, you may be able to use it to pay for a new mattress if your doctor recommends it.
Look for a Trial and Return Policy
Most online mattresses companies offer trial periods. Some offer a full year. Many brick-and-mortar companies provide trial periods now too.

If you are nervous that you won’t like your new mattress, compare policies. While the 365-day trials are generous, three months is usually more than enough time to determine whether you like your new mattress.

In addition to the trial period, look at the return policies. Most offer free returns, but some charge a fee.
Read Customer Reviews
Without trying a product yourself, the best way to get an idea of whether or not you’ll like it is to read reviews from real customers.

If a customer doesn’t like a product, he or she is usually honest in a review. If they love the product, they’ll give details about why.

Keep in mind the best mattresses to buy online isn’t necessarily what someone else deems the best mattress. However, if a company has a fair number of negative reviews, you may want to find a different option or see if the negatives are going to be an issue for you.
Set a Budget
As with any new purchase, the price is important.

Set a budget at the beginning of your mattress hunt. Compare prices for various mattress companies. Consider any that come in under budget and add a few that are slightly over budget in case you decide to stretch it.

If you see any that are way outside your budget, eliminate those companies from your consideration list.
Mattress FAQsWerner Heiber / Shutterstock

If you’re in the market for a new mattress, we’re sure you have a few questions.  Below are some frequently asked questions about mattresses and their answers.
What Are the Average Mattress Sizes?
There are six sizes of mattress: Twin, Twin XL, Full, Queen, King, and California King.

Standard mattress sizes are:

Twin: 38″ x 75″
Twin XL: 38″ x 80″
Full: 53″ x 75″
Queen: 60″ x 80″
King: 76″ x 80″
California King: 72″ x 84″

The size can vary slightly between brands.
Do You Need a Box Spring?
Not necessarily.

A box spring can support a mattress and help protect it. While some mattress types require a box spring, others do not.

Before purchasing a mattress, check to see if a box spring is required.
How Long Should a Mattress Last?
Mattresses longevity will vary. Here is how long most mattresses like:

Hybrid mattresses: 6 years
Innerspring mattresses such as coil-on-coil: 8 years
Foam mattresses: 10 years
Latex mattresses: 15 years

Keep the above in mind as a base, and then add or subtract years depending on use.

If a foam mattress is in a guest room and is only used a few times a year, it should last longer than 10 years. However, if a foam mattress is used nightly by someone who is overweight, the mattress may last less than 10 years.

Bodyweight determines the amount of pressure on the mattress, so heavier people exert more pressure than lighter-weight people. As such, heavier and taller people will need to replace their mattress more quickly than a lighter-weight person.
When Is the Best Time to Buy a Mattress?
If you can, wait for the retail holidays.

While mattress sales may occur at other dates, these are typically the best days of the year to find the best mattresses to buy online deals.

Key retail holidays include:

Memorial Day
Labor Day
Columbus Day
Black Friday
Cyber Monday

If you see that a big store is having a sale, chances are the mattress companies will have to have sales to keep up with the competition.
How Often Do You Need to Flip a Mattress?
How often you need to flip your mattress depends on what kind of mattress you have.

Decades ago, we were told to flip our mattresses every six months. But now, some mattresses don’t need flipping.

If you have a mattress with a one-sided design, you should never flip your mattress. You will know it has a one-design because the two sides will not be identical.

Most mattresses are one-sided as they feature a pillow top or Euro top or have different types of layers.

Let’s take a look at the different types of mattresses and whether or not you need to flip them:

Coil-on-coil mattress: You don’t need to flip most of these mattresses. Rotate them once or twice a year.
Foam mattress: You don’t need to flip most, but rotate them once a year.
Hybrid mattress: Some hybrid mattresses are dual-sided, meaning they should be flipped once or twice a year. Others are one-sided that you should never flip. Rotate these once or twice a year.

How Do You Clean a Mattress?
In addition to bodily fluids, dust mites, mold, mildew, pollen, oils, dirt, and more can build up in a mattress. As such, it’s important to clean your mattress.

Some people clean them seasonally while others do it once or twice a year.

Cleaning a mattress is easy and requires a few simple steps:

Vacuum the mattress
Deodorize it
Remove any stains
Flip the mattress and repeat the steps.

If You Have Bed Bugs, Do You Have to Throw Away the Mattress?
No.

Bed bugs are blood-sucking creatures that tend to frequent major cities. They cause red, itchy welts on the skin and unfortunately are hard to get remove.

Thankfully, there are ways to get rid of them for good – even from your mattress.

How Do You Dispose of a Mattress?
Most online mattress companies offer mattress removal service when you purchase a new mattress.

If you purchase a mattress from a company that will not offer to remove your old mattress, disposing of it can be tricky.

Different cities have different laws regarding mattress removal, so research your local ordinances. For instance, some cities consider mattresses to be regular garbage and allow you to place it with your regular waste. Others require you to take it to a recycling center.
