Very happy to receive this very heavy compact box. Yes, it weighs twenty nine pounds. I had to have help with it. But so worth it! Inside, it held a six inch gel mattress. It exceeded my expectations one hundred percent! I can not tell you how nice this is; and so very comfortable. Pretty also. It is made of medium gel memory foam and bamboo charcoal infused. I got the full size one. I put it on top of an older mattress and it just renewed  my bed as far as a great night sleep. This is the answer if you are not ready to spend thousands of dollars for a complete foundation for a bed. I really love mine and I think you will also. Remember, Wayfair sells only the very best.
