Perfect for renewing our 15 year old Sleep Number bed, it's just like brand new. We were looking at one on sale at Costco and after checking the reviews at independent sites decided it was not very high quality. Decided to check here and then we researched the Lucid brand. Same review sites gave it high marks. The smell issue has been mentioned, I am very sensitive to chemical odors but could barely detect it and it was gone the next day. Ours only took over night to completely fill out. Our delivery was messed up and was a week late, still $25 cheaper than Costco's sale price and Wayfair gave us a 10% off code for the delay so very happy and satisfied.
