Novaform Comfort Grande Opinions

Hi. I’m looking for opinions on a Novaform Comfort Grande mattress that is sold at Costco. The reviews are very good on Costco’s website. CR tested it and said it held up well in their 8 year simulation test. Here are the specs that I have:

Top layer: 3-inch EVENcor GelPlus™ Memory Foam (3 LB density)
Middle layer: 3 inches of Premium Support Foam with air channels (2 LB density)
Bottom Layer: 8-inch Premium Base Foam (2 LB density)

The foam is made in the USA and is CertiPUR-US® certified. The mattress is currently on sale for $560 in-store. It seems like a good price based on the review but I’m just curious on how well it will hold up with those foam density’s. I don’t mind spending a little more for something better if this mattress won’t hold up. I’m 5’10" and weigh 160 LB’s so would not be putting a lot of wear and tear on it due to weight. Thanks!

I’m not a fan of memory foam but buying from Costco means that when it does fail you should be able to return it for refund or a new mattress. I’m a latex expert and I have to say that I hear over and over again from Costco members about the failure of their Novafrom mattresses and toppers. Maybe they’ve improved the quality recently.
