I had a very positive experience buying from Everrest Mattress. They only carry five models of mattress, and the owner explained the pros and cons of each one, without trying to upsell us to the most expensive model, other than to explain that the two cheapest models were single-sided, and not really intended for everyday use - more of a guest-bedroom mattress.
The prices at Everrest were great - far less than half of Sleep Country USA. The mattress we ended up with, the second-highest in their line (Premium Pillowtop), cost less than any mattress on the showroom floor at Sleep Country, and it is more comfortable than any of the Sleep Country mattresses I tested.
They were able to deliver the mattress the next morning; my wife received the delivery while I was at work, and she said the delivery men were helpful and prompt. They took away our old mattress for no additional charge. I think delivery used to be free, but now the cost is $20 due to diesel fuel prices.
Great price, great mattress, friendly staff, and no-pressure showroom. A+
