  • Love it
I was super nervous about ordering a California king mattress online; I mean, you can't exactly bounce on it in a store first! After checking reviews and comparing, we decided this was the one. Honestly, I'm so glad I did; it's incredibly comfortable and supportive. The whole experience turned out to be much better than expected! ... show more
