I purchased this foam topper to help with pressure points on my knees and other parts of the body due to Arthritis. It has helped allot. It is a thinner one but it makes the bed even comfier ! It came packaged super good and for me when I opened it I did not have a smell at all. I opened it and put it under my mattress pad and it's been great ! If you do not want to spend allot or cannot spend allot I would def. recommend this.I have had nothing but great experiences with wayfair and will continue to order from them !
