I'm a mattress buying novice. I also hate buying things that require you to try-before-you-buy. I also seem to give explanatory information about myself before reviews. Anyway.
I had a lot of anxiousness about buying a mattress. If it's terrible, you'll be spending a large proportion of your life in misery until you fix the problem. Who wants that? Especially for something that can be as expensive as a mattress?
These people were great. They patiently answered all of my mattress questions and treated me like a valued customer - both times I called, the man on the phone remembered my name (and number!) and took care of me. When I failed to buy a box spring (why oh why did I think I could go without a box spring??) they were able to take care of me over the phone and get me a box spring in the SAME day. Within hours, even. They even helped me set up the mattress that I DIDN'T purchase from them, which blew me away.
Their professionalism and friendliness are excellent. I will recommend them to everyone who's in the market for a mattress, especially students, because their student deals are fantastic.
