we used to have one, but they closed.

One interesting thing that sleeplikethedead.com pointed out is that people who buy their mattresses online without testing them out are more satisfied with their purchases than people who go to a store and try them out.
They gave two reasons for this counter-intuitive point. First, online buyers do more research and are more educated purchasers. And second, the store experience is so useless, the 5 minutes the average buyer spends lying on a mattress doesn't help them choose a mattress with any success.
