Warning: our houseguest won't leave

Bought to upgrade our guest bedroom. First houseguest stayed for three nights instead of the one she had planned. Second guest appears to be staying permanently. This is a five star review because we really like the second houseguest, but I suppose this could have downsides if houseguest is someone you are less enthusiastic about.

Finally found a winner

After trying several expensive mattresses, I think I finally found the one I most like and works well for me. I was able to sleep on one before buying this one for several weeks and didn't wake up with aches and pains. It is firm, but not too firm and it feels like it will maintain its shape. What's even more amazing is that it is 1/3 of the price of the other mattresses I tried and sent back.

We finally found the one!

We have struggled to find the "right" mattress for my husband for years. While at an Airbnb we slept on this mattress for three days and we both loved it. Glad to have a 100 night trial but so far, after about one month we think we've found the winner!
