Don't buy this bed! It's a big waste of time and money. My mother purchased 3 for my 3 youngest children a few years ago. My mother maintained they were good for back support, but in my opinion they were hard and surprisingly cheaply made. First the beds started sabbing on the sides from sitting on the edges of the beds. One bed started to unravel around the stiched edging. Another started sagging deeply in the center and a coil broke through. One bed was replaced under warranty which was an exhausting and tedious process. Within 1 year the children all had brand new Sealy and Serta beds. I will never go back!! Comfort No comfort value added. Only better than sleeping in a chair. Support Not enough padding. If you get stuck with this bed you will need the best neck pillow, and perhaps a body pillow too. Firmness Super firm, just short of laying on a beach blanket on the sand. Durability Experienced unraveling threads, sagging centers, and saging edges and coil spring malfunctions., all within the first year.
