After hundreds of hours of testing, we have four to recommend.
We’ve also included descriptions of a few slightly firmer mattresses for side-sleepers who frequently shift onto their back and stomach or those who simply prefer a more-supportive feel.
You can read more about these picks and others in our guides to the best foam mattresses, the best hybrid mattresses, the best innerspring mattresses, and the best cheap mattresses.
Our pick
With a thick quilted top and the highest foam density we’ve found in an online mattress, this mattress feels more substantial and durable than many of its cheaper counterparts.
For side-sleepers who like a sturdy, memory-foam bed, the Loom & Leaf (Relaxed Firm) should deliver a better night’s sleep than most of its online competitors.
It’s also one of the plushest yet sturdy-feeling foam mattresses we’ve tested. The quilted, padded top forms a nuanced cradle for the shoulders and hips, and the durable foam layers help keep your spine aligned. Its foam is also denser than that of cheaper memory-foam mattresses and more likely to hold its shape over time.
Sold by Saatva, it comes with a generous 365-day trial, so you can return it if it doesn’t work for you (although Saatva charges a $100 “processing fee”).
Our pick
The Saatva, which pairs a classic innerspring bounce with a cushy-but-understated Euro top, appeals to those who want to feel nestled in rather than engulfed. But it doesn’t have the best motion isolation.
Side-sleepers who don’t like the hugging sensation of memory foam may like the innerspring Saatva Classic (Luxury Firm).
Two types of coils keep your spine suspended and allow for easy side-switching. And the Euro top—a layer of padding sewn underneath the fabric cover—helps cushion your shoulders and hips without producing that assertive memory-foam embrace.
It’s one of the few innerspring mattresses we’ve found that comes with a generous 365-day trial, so you can return it if it doesn’t work for you (although Saatva charges a $100 “processing fee”).
Our pick
The Leesa Sapira Hybrid combines the best parts of memory-foam and spring mattresses. It offers better cooling and has a thicker cover than the competition, all at a great price.
Side-sleepers who prefer a little bounce in a firmer, memory-foam mattress will likely find that the Leesa Sapira Hybrid offers the best of both worlds.
Its 1,000-plus individually wrapped coils make your body feel lifted, even as the memory foam loosely hugs your shoulders and hips. And if you sometimes sleep on your back or stomach, you’ll appreciate that the Hybrid has just enough springiness to make shifting positions easy. The Leesa Sapira Hybrid’s dense foam also makes it a good pick for people who weigh more than 200 pounds.
It comes with a 100-day trial.
Our pick
This Costco favorite is made from layers of foam that are as dense (and probably as durable) as the foam in mattresses that cost twice as much. Testers loved its cuddly yet supportive feel, though some found it to be too firm.
If you’re a side-sleeper who needs a pillowy cushion for your shoulders and hips but prefers a firmer mattress, the Novaform ComfortGrande is a good choice.
When you purchase this mattress online, it’s well under half the price of the Loom & Leaf (Relaxed Firm), our higher-end, all-foam pick; it’s even cheaper if you buy it in-store (non-Costco members pay a 5% fee). The Novaform provides a loose, cuddly sensation without the pronounced memory-foam sink, but it’s a bit stiffer than the Loom & Leaf. (The Novaform’s foam densities suggest it will be durable, too, at least for people who weigh under 200 pounds.)
The Novaform ComfortGrande comes with a 20-year warranty. And, thanks to Costco’s generous return policy (the best we’ve seen), you can arrange for a free pickup and full refund at any time.
