The A3 is medium-firm, but you can go with the A2 if you prefer more support or the super-soft A5. Because ultimately, the best mattress for you depends on your personal preference.

Best reversible all-foam mattress in a box

Layla Sleep

Choosy sleepers will love Layla Sleep’s reversible foam mattress that lets you choose between a soft and a firmer side. This bed is perfect for anyone who’s new to foam mattresses and might be unsure about which firmness level they like best. It’s also great as a guest bed to suit various sleeping preferences.

Rounding out the Layla mattress’s features are copper-infused foam layers, a 120-night risk-free trial and an unprecedented lifetime warranty.

Most popular mattress in a box

Purple

Purple remains one of the most popular online mattress brands, and it’s easy to see why. Its patented Hyper-Elastic Polymer layer is unlike any material that other brands offer. It’s super cushy, super bouncy and, according to thousands of customer reviews, super comfy.

In fact, this bed was such a fan favorite that the company decided to release three new models, each with varying thicknesses of Hyper-Elastic Polymer, combined with foam and/or coils.

Best mattress for camping

Lightspeed Outdoors 2-Person PVC-Free Air Bed Mattress

This inflatable air mattress is ultra-portable, has a high resistance against abrasions and comes with a battery-operated pump — making it a good pick for campers. It comfortably fits two people and features built-in handles on either side so you can stake it down to prevent your bed from sliding out from under you when switching sleeping positions throughout the night.

Best bed-in-a-box for kids

Nest Bedding BKB – Big Kid’s Bed

Nest was the first online mattress brand to come out with a smaller foam mattress designed specifically for kids. It’s made of two supportive, CertiPUR-US certified foam layers, is made in the USA and does not contain any toxins. This bed gets rave reviews online and can be placed on any bed frame, including bunk beds.

Best mattress for stomach sleepers

Saatva

The trick to stomach sleeping is to have enough support for your hips without forcing your spine into unnatural positions. The Saatva mattress is comprised of a combination of foam layers and pocket springs, giving stomach sleepers the support they need while still offering some bounce and flexibility.

This mattress is available in three firmness levels, is made of eco-friendly materials and is available for nationwide in-home delivery and setup.

Best mattress for small rooms

The Platform Bed by Casper

If you need to save space, we recommend a streamlined platform base like Casper’s new model offers. It gets your mattress off the floor without expanding its footprint, plus it’s super stylish and available in two colors. And it still qualifies for a 30-night risk-free trial and free return pickup if it happens to not work out for any reason.

How to choose the best mattress

Choosing a mattress comes down to a number of factors: how you sleep, what size you need and whether or not you suffer from conditions like back pain or chronic snoring and sleep apnea. These will all impact what style, firmness and size mattress you should buy. Before shopping around, consider these factors:

  • How you sleep. Do you sleep on your back, side or stomach? This will affect how firm your mattress should be. If you sleep on your back, opt for a medium-firm mattress, which will help to support your entire spine. Stomach sleepers should opt for a firm mattress for the same reason, while side sleepers are better off with a softer mattress to allow maximum movement and comfort.
  • Size. Are you purchasing the mattress for yourself or for a family member? Do you intend to share or sleep alone? If you’re looking to purchase a mattress for yourself or for a child, you can afford to choose a smaller size. But if you intend on sharing with someone else, you’ll want to look for something larger that meets both of your sleeping preferences. Standard mattress sizes include twin, full, queen and king. Extra-long twin and California king are also available from many mattress retailers.
  • Back pain and chronic conditions. If you suffer from back pain or have a long-term condition that affects your sleep, having the right combination of mattress and pillow can work wonders.

Bottom line

Picking a new bed is a big deal — after all, you’re going to be spending lots of time in it. But with a little research and a generous risk-free trial offer, you could be well on your way to laying your head on the mattress of your dreams.
