I bought this mattress from Costco last month on sale. It was conveniently packaged and fit in the trunk of my car. Waiting for it to inflate after cutting it open was another matter. It never did fully inflate and there was a hard ridge down the middle of the mattress that ran from the head of the mattress to the foot. I called Sleep Innovations and after sending them some items, they sent me a replacement mattress in a few weeks. After 72 hours it was MOSTLY inflated, although there were a few areas that weren't completly expanded (corners and a few areas on the edges). I slept on it for the first time last night and it was solid and uncomfortable. Very similar to laying on a sack of flour or sand. The mattress comes with a heavy inner wool-type layer of fabric around it, then the exterior cotton zip cover. I'll be removing the wool fabric tonite to see if that helps. If anything changes I'll update this rating.

I bought a novaform elite at costco Iwanted a memory foam mattress but did not have a big choice where I live I saw the novaform at costco months ago but they did not have one out of the box and on the floor and would not take one out of the box the mattress comes vacuum packed in a box that is 4 feet high and 2 feet wide and 1 foot deep this is a 12 inch thick queen size mattress
9 inches of 2 lb foam for the support base and 3 inches of memory foam I called novaform and was told the foam is from foamex and all made in the USA
Costco had a $50.00 rebate so the mattress went down to $485.99 so I got one
I got it home and opened the box and it started to expand the mattress was ready in about 6 hours and I used it that night very little odor and it was on the first night only
I have just had the Mattress a little over 3 weeks and I love this Mattress I sleep so good
I am 5-8 and about 175 and sleep on my stomach and side but on this mattress I can also sleep on my back
I was using cotton flannel sheets but it seemed hard tol roll around or change positions so I put a micro fleece blanket over the sheets and can move easy and the fleece grips the sheets and stays right in place ( so comfortable )
My only concern right now is how long the foam will last
If the feel of the mattress changes or my opinion changes I will update
