After going to multiple mattress stores, doing tons of online research and laying down on several high end beds; I realizing that a medium firm gel memory foam mattress was exactly what I needed for my severe neck problems/lower back pain due to a very bad car accident. I am on disability so I love with a fixed income and couldn't afford the high price at these high end stores. I saw the reviews and decided to go with this one. The mattress arrived quickly, had a friend help me carry the box upstairs. We unwrapped it and thought it was going to be very thin. Within minites, it began expanding and started to look like a real mattress. No smell was identified and we left the house for 6 hours. Upon returning home, the mattress was fully expanded. I literally had the BEST sleep in years!!! I am a side/back sleeper and my hips and shoulders usually hurt when I wake up. Not this morning!! The mattress conforms to your body. It's like sleeping on a cloud pillow. It's better than the ****$ mattress they tried to sell me at the high end mattress store. I am in love with this mattress. You will never be able to beat the price. I can't believe I waited this long to purchase a great mattress. You will not be disappointed.....best, best, best sleep ever without agonizing pain upon waking!!!!
