I think the quality of the product is great. I was surprised that a bed in a box still was able to have springs. I also was worried with it being 8” it would be a little too small but it's actually perfect for a bed frame or something of the sort, especially if you put a topper on it.

If I hadn't unpacked this mattress myself, I'd never believe it came out of a box! My partner and I had been worn down from restless sleep and had plenty of aches %26 pains from our previous bedding. Last night was night 2 with this new mattress and I feel completely different! This mattress is very supportive and comfortable for sleeping in any position. It was a fantastic choice!
