This mattress is amazing.  This was our first purchase from Wayfair and we were nervous about it, as we wouldn't get to see the mattress before we used it.  But there was no need to be nervous, It was the best thing we have done.  The quality is amazing and we are having the best night sleep in years.  I found the delivery really good as well, and the man was so lovely he could see I have a back problem and made sure it was in the room of my choice.  5 star service and delivery.
