In the past, buying a mattress always meant visiting a physical store and trying one out, and while that’s nice, lying for three minutes on a mattress in a store just isn’t a great way to know whether that mattress will really be comfortable for the long haul. Online sales are now a great way to get a good mattress: you can read real reviews, and most online sellers now offer guarantees that let you return the mattress easily if it’s not working out for you. If you’re on the hunt for the best online mattresses, this is what we’ve found.

Three Best Online Mattresses

Nectar Memory Foam

If you’re just looking for something that will come quickly and can be had at a discount price, the Nectar could be a good choice. This mattress comes with a 365-night home trial guarantee, is made with CertiPUR-US certified foam, so it won’t stink to high heaven for weeks after you unbox it, and comes with free shipping and returns. This one has a moderate firmness level.

The downsides are that it tends to sleep a bit hot, and it won’t really provide good support for anyone over about 230 pounds.

Plank Firm

This won’t be the right bed for a lot of people, but if you’re one of the minority who really wants a firmness bordering on “plank of wood,” you might want to check this one out. It is flippable, so you get “firm” and “really, really firm” depending on the side you choose.

The Plank Firm is a high-profile bed, so be aware that it mostly works with adjustable power bases and tall headboards. This bed is best for those who sleep hot or for people who like to lie on their backs. The firmness will probably be too much for anyone who sleeps on their sides or who shifts around in the night. This one comes with a 120-night trial period, and you must keep it for at least 30 nights.

The Saatva Classic

The Saatva Classic is the most versatile and high-performing of the mattresses we’ve tested. It comes in three firmness levels, has a 365-night trial, and comes with a lifetime warranty. It works great for couples, and it’s a hybrid that offers the best of foam and coil sleeping. The coils are strong and encased in pockets that keep movement transfer down and extend the longevity of the coils themselves.

The upper foam layer is CertiPUR-US certified and infused with a cooling gel to solve the problem of hot sleeping that so many foam mattresses have. Plus, Saatva has put a special quilting in the middle third of the bed to offer the most support where you need it most. Saatva will do free white-glove delivery and setup and will take away your old mattress and foundation for free, as well.

There are a lot of online mattresses out there, and these three are just a few good ones to consider. Thankfully, online mattress makers now offer very generous trial periods, so you can try a mattress at no risk.
