The thing is I just can't buy a mattress without lie on it first. So i went to a physical store and look for something "firm" and "comfortable." The innerspring of "Beautyrest Silver 14" BRS900-C Extra Firm" provides great support while the top memory offers comfort. Then I searched on-line looking for the best deal which leads me to Wayfair. Price is $361 lower and delivery is fast. When I was about to write a review, I noticed that there's a SALE going on. So I called Wayfair Customer Service team and the difference was refunded to my card.  This made my first order experience with wayfair GREAT.
