A super comfortable mattress! It arrived quickly via UPS in a tall skinny box. However, due to severe arthritis pain and then hip replacement surgery, I had to rely on help from a friend and her teenage son to unbox my new Alwyn Home mattress. It smelled a bit like chemicals but all new mattresses do. After it aired out in the garage for several days, they carried it up 2 floors to our guest bedroom. As a surprise for me post surgery since I could not do much, she also put on the mattress pad, sheets, and comforter so when I made it upstairs to check out the new mattress, our cat Oscar had already claimed it! Cats are the kings of comfort so if they like a mattress, I know it is great. But since others might want the human perspective, I have slept on it while recovering from my surgery and it is SO comfy! The medium firmness is perfect for people like me who want a too soft mattress but must have something firmer. Also, I sleep very hot but I remained cool through the nights, even with our heat on. Now I wish we had switched out our main mattress but I did not know this one would be as good or better than the great Wayfair mattress we bought in 2019 when we bought our new home. Once I am recovered, I plan to switch the mattresses so that my husband and I have the new wonderful mattress in our room. A Wayfair win as always and I can really recommend this ten-inch Alwyn Home mattress!
