This is a very soft memory foam mattress. Its only being used for a guest bed. I definitely prefer a mich firmer mattress for myself, but everyone is different. It certainly works fine for my purposes and if you want a soft, squishy memory foam mattress, you'd likely love it.

Hello Sarah! Thank you for sharing your feedback! We’re glad to hear the mattress works well for your guest room. This model is designed with a dual-layer foam structure — a soft memory foam comfort layer combined with a high-density support foam base. It’s meant to provide a balanced feel between contouring and support. If you ever feel it’s a bit too soft for your preference, you can try unzipping the mattress cover and swapping the order of the two foam layers. Placing the support foam on top will create a firmer and more supportive surface — a simple way to customize your comfort level. We truly appreciate your thoughtful review and hope your guests continue to enjoy restful nights!

Bought 2 of these for my children, they are great. Packaged well, came with a little plastic cutter to open without cutting your matress. Foam expanded well but to sit on the end/edge of the bed I felt I was sinking and going to mess up the matress so not sure if I would recommend for adults. Also throw a matress cover on them before kids decide to play on them, the black fabric cover has pilled and created a hole within hours of having it out to "grow".
