This mattress arrived in just a couple days and was well packaged. It’s a little on the firm side but since it’s only 5 inches thick that helps with support on a platform style bed. But keep in mind it is not very thick. Works great for my son’s platform bed and he is 12.

Firm yet soft comfortable mattress

I've been wanting a new mattress to help my husband sleep better and to relieve my back pain in the mornings, and this one has been a great choice. I went with the 12-inch Queen, and the size is perfect and it arrived incredibly fast. Setup was quick and easy—just unbox it, and it expanded within minutes. The comfort level is just right—firm for support, yet soft enough to feel cozy. I also tend to get hot at night, but this mattress stayed cool and comfortable throughout the night. We both noticed a difference right away and woke up feeling more rested. My dog loved it as well! Overall, I’m very happy with this purchase and would definitely recommend this mattress!
