The mattress was quite comfortable.  Soft on one side and more firm on the other side.  I chose to use the firmer side but after a few weeks, it began to crush where my body lays. The memory foam lost its memory.  

I followed the instructions and did not lay on the mattress for 48 hours. 

It may have been a one off defective mattress but its what happened. 

Wayfair made it right. Their service is amazing.
