Ultimately, most people want something in between—a mattress that’s supportive, pressure-relieving, and durable, but that doesn’t empty their bank account. That’s where Costco’s Novaform ComfortGrande comes in.
Like many Costco-exclusive items, the Novaform ComfortGrande gives you a lot for your money. Many of the cheaper mattresses we’ve tested—and even some of the more expensive ones—aren’t nearly as thick. At 14 inches, the Novaform is one of the loftiest mattresses we recommend, so it looks and feels more substantial than its price would suggest.
Our pick
Novaform ComfortGrande
This Costco favorite is a great value, made from layers of foam that are as dense (and probably as durable) as the foam in many of the mattresses that cost twice as much. Testers loved its cuddly yet supportive feel, but some found it to be too firm.
The widespread appeal of the Novaform ComfortGrande is that it’s built to work for almost anyone. It might not be your absolute favorite, but it’s the only budget-friendly mattress we’ve tested that we think could reasonably last the 10 or more years mattresses are expected to.
The Novaform ComfortGrande has a cuddly feel, without a tight memory-foam hug or exaggerated sink. I tend to prefer slightly softer mattresses, but I still slept perfectly well on my side on this mattress. It has a medium-firm feel that should work for all sleep positions.
We usually judge the durability of an all-foam mattress by analyzing its foam densities, and the Novaform ComfortGrande’s density of 3 to 3½ pounds per cubic foot puts it on a par with mattresses priced at $1,000. Even mattresses that cost hundreds more than the Novaform—Studio by Leesa, Puffy Mattress, and Nectar Original—use less-dense foams. There’s certainly some nuance to durability that isn’t captured by foam density, but this measurement still underscores the Novaform’s great value.
The mattress also comes with Costco’s fantastic return policy—so if you don’t like it, you can essentially return it at any time, for any reason. And the company will pick up the mattress free of charge. Even in the mattress world, where a 100-night free trial is the norm, Costco’s policy is difficult to beat.
