We bought a Glen Rose Queen for $519 on sale for $419 3 years ago at Sams Club. It is springs, Memory gel and plush cool foam on top. I'm 275lbs. so we probably didn't rotate enough and it was starting to sag on my side. Still comfortable but with a 10 year warranty and Sam's great return policy we decided to take it back for a trade. The new one like ours is now called Glen Moor and now called a Hybrid. $499.00. They wouldn't let me pay the difference from the sale price and in fact wanted to refund me from the list price $519-$499. I asked if they would just let me trade across and they agreed to that. With higher spring count (866) it is firmer but with memory gel and cool foam top it is still plush. Very comfortable. We will rotate every 6 months this time! Lists for $1299 on Serta's web site. Very happy with the mattress and the deal from Sam's Club!
