Novaform 14” ComfortGrande Advanced Gel Memory Foam Mattress from Costco has been the best mattress I’ve ever used. During the $100 off sale the Queen was $399 and king was $499

I am In the camp that a mattress is something that okay to splurge on as you use it every single day for hours. With that said,I was recently shopping for a mattress and came across the Novaform 14” ComfortGrande Advanced Gel Memory Foam Mattress at Costco for only $430 bc they were running a $100 off special . It was way more comfortable that the $2000 mattress I was looking at. I have it for 2 weeks so far and absolutely love it.

Purple for the splurge. Novaform 14” ComfortGrande Advanced Gel for the budget option. Have had both and am a side sleeper. Buy The purple if you don't plan on moving for a long time, and a very solid bedframe. Those mattresses are super heavy & dense, and have no structure. It's like moving floppy sheet metal. I miss mine a ton though. Novaform for ~$500 will fill your needs and is a super solid option, I'm on year 3 with mine and still sleeping great on it. Both mattresses have mediocre edge support though.

We've had the Novaform 14” ComfortGrande Advanced Gel Memory Foam Mattress for a little over a year and it's been one of the best beds I've slept on given the cost. Plenty of room for my fiance and our 2 kittens. Stays cool, firm but not overly firm. My back issues have mostly gone away

Agreed, we are really happy with this mattress too and the price is great. It also solved my back issues! We have had it just over a year.

I believe its the Novaform 14” ComfortGrande Advanced Gel Memory Foam Mattress. Bought it for the motorhome on a long trip. Liked it so much we bought the same one when we got home for our bed at home.
