Mattress salesmen are greasier than used car salesman.

That said, I ignored Sleepy's phony price guarantee and played one Sleepy's against another. I went to three area Sleepy's showrooms and bought from the one who beat out the other two in price. I first acted like I had not been to any other showroom to see what I would be quoted. Then if the price was higher than what I'd been quoted I would ask if they could beat that quote and so on. By the time I got to the 3rd Sleepy's the salesman was eager to beat out my lowest quote. This guy deserved the sale - He found me the mattress at the "warehouse" price, which was about 30% cheaper than the lowest "sale" price I had been previously quoted. I did have to go pick up the mattress at the warehouse, but it was well worth it. Oh, and it's a Beautyrest and I've had it for 2 years with no complaints. I did buy a memory foam topper, though. Save your money and buy a less plush mattress and use memory foam. It'll make your mattress feel just as comfortable for a lot cheaper since a lot of mattresses use the same or similar core but charge a premium price for the attached topper (just be sure to check that out first). Plus if you use your own topper it's easy to replace if you want to.
