My Stepdaughter convinced me to buy and try this mattress out due to the fact that she had purchased one several years ago. WOW, am i surprised the mattress beat all of my expectations. I had purchased a Cal King for my Master bedroom & this for the guest bedroom, The Cal king was from a Mattress store chain and cost close to *** . I was amazed that this one cost a fraction of that and is a better quality mattress, LOVE IT
