This has literally saved my back. My matress is less than a year old so I didn’t want to change it, but I hate the feel of it. I was waking stiff and sore and wasn’t sleeping soundly as I was so uncomfortable. This mattress has saved my sleep. I can’t recommend it highly enough. I am now waking refreshed after an amazing and comfortable sleep. Wayfairs products are always excellent, I can’t fault any purchase I have made.
