Moved in to a new house and wanted something  as a stop gap arrangement  for my son's bedroom   until we buy a good memory foam mattress. 
Quick browsing on wayfair led us to this mattress . The purchase experience was fast with timely shipping . 

The product- The product comes rolled and compressed . The manual says the mattress will  come to shape in 48 hours. However it has not come to the boxy shape shown in the pics . yet after 15 days. 
Comfort - But the comfort this mattress provides is superb. Folks using regular mattress will feel different when  sleeping on this for the first time  and should get accustomed to this in a day or two . 
The mattress it self is neither firm nor soft . Plus point we have a platform bed . 
We do not think we will be buying the memory foam mattress now as my son loves it . Good support and comfy . No back problems .  
Recommended if looking for something else .
