Amazing quality

Great quality for price! We were looking at a discount mattress store and couldn’t find a single king size for less than $500 and this one is just as nice as one of those. It was easy to unbox and almost immediately got to 14”. Once opened it was already to 13.5”. It is on the firmer side but once we sleep on it a little longer I think it will be perfect.

Mattress in a Box

I bought one for my sister in Arkansas and when we visited and slept on the mattress it was so comfortable and lived up to the advertisement that when one person changed sleeping position you didn't feel any effect of the movement. Then, my other sister ordered a mattress in a box also, but a different brand. Her children in Texas said it was comfortable. Another plus is that it was easy to put together the base frame.
