Great Mattress – Comfortable and Conforming

I received the item quickly, and it came well-packaged in a small box. It took a day or two to fully expand to its normal thickness, but I was able to sleep on it the first night without any issues. The mattress conforms to your body—you really melt into it—which makes it very comfortable. It's perfect for me, and I'm happy with the purchase.

Much better than I expected!!

I was expecting this to be a small mattress top sort of thing you just add to a bed but it's basically a full mattress size but I'm comfortable material that seems to almost cuddle you while laying on it! Definitely recommend ten out of ten and would definitely buy this again!
