First off, I have to comment on the design. The mattress itself is just so beautiful I almost didn't want to cover it with a sheet! It's this beautiful blue and has a fun design on it. The material they used is also very soft. Now on to the mattress itself. The mattress was so comfortable! I wasn't sure if it was going to be too firm for me, but the medium was absolutely perfect. I felt like Goldilocks when she found the "just right" bed I slept like a baby (with 3 kids that's always a plus) and woke up without any weird kinks in my neck or any discomfort. I would absolutely recommend this bed!
