“completely transformed our RV sleep experience”
I ordered the mattress and it arrived early. I was so excited to test it out. We opened the box in the basement and set it up right away. We couldn’t wait until the weekend to sleep on it because we were both so excited about trying out a new mattress… Our first night’s sleep was AMAZING! We could tell that this was going to be way better than our old spring mattress! We ordered another one for my parents (and they love it too!). We're ordering another one for our new king sized bed soon! Everything about Mattress Insider is fantastic.
