Purchased this bed for my father. It’s been three days and he’s in love with it. It’s a very heavy, good quality mattress, and I have no complaints by with confidence.

This bed has made a major adjustment for my sleeping. The last mattress we had was ok but I slept maybe four hours and would wake up sore. After two years we got this and I wake up feeling great and sleeping 7 hours easy!

This is one of the worst disappointments I have ever had. This product should be labeled as dangerous for kids. The edges are so poorly made that you could literally fall out of the bed if you get too close to the edge.
