by Quick answer: The Novaform 14" ComfortGrande is Costco's all-foam gel memory foam mattress, about $699 for a queen with a 20-year warranty. It offers a deep contouring hug and good motion isolation, but there's no dedicated sleep trial, longer off-gassing, and you need a Costco membership.

What Owners Report
Testers rate it well for motion isolation and edge support, with relatively neutral temperature for memory foam thanks to gel infusion and air channels. Side sleepers under ~230 pounds tend to like the pressure relief. Criticisms include a strong off-gassing odor that can last up to two weeks, a deep "hug" feel that not everyone enjoys, and one reviewer measuring the loft closer to 13" than the stated 14".
The Saatva Alternative
If you'd rather not buy without a real home trial, the Saatva Classic ships with a 365-night trial so you can test it risk-light, plus a lifetime warranty and free white-glove delivery. As a coil-on-coil hybrid (queen around $1,995), it sleeps cooler and more supportive than a deep memory-foam hug, and there's no membership required.
Bottom Line
The ComfortGrande is a fair-value memory foam mattress if you're a Costco member who loves a contouring feel and can tolerate some off-gassing. The lack of a dedicated trial is the main drawback to weigh.
Bottom line: Novaform's ComfortGrande is solid budget memory foam, but no sleep trial and a deep-hug feel make the Saatva Classic the safer, cooler choice.
