We chose a twin to try out as we are interested in a king size. After sleeping on twin mattress in the guest room for a week, we decided it's ok but we need to do more research before we pur hasr a king size mattress. We are checking out a similar Casper brand.
I really like this mattress. I got rid of the sleep number bed because it just wasn't that great. I used to get back and head aches and I used to have bad night sweats and now...all gone. Even my dogs seem to like it better....
