Mattresses, what’s your recommendation and why?

If you are in TX or CO, Texas Mattress Makers (.com) will make you any size/shape mattress to fit the space available for the same price as their showroom mattress. Denver Mattress will do the same but I am not sure of the pricing. We have the Texas Mattress Makers unit and we were able to customize the thickness and the topper material as well as having the foot of the bed rounded to the exact shape of the foundation.
