We bought Bed in a Box at the recommendation of this forum and we love it!! No more hip pain! We bought the Original PacBed RV Queen. We bought the 11" thick mattress because it said it was more firm. And we added the gel which makes it cooler. So glad we did. It comes delivered in a box, weighs about 70 pounds. We removed the old mattress (the most difficult part) brought the box in, put the box on the platform, Opened the box. Next step is to CAREFULLY removed the shrink wrap without cutting the mattress!! I would not use a box cutter. We used scissors. There is a video showing how to properly do this. Voila! instant bed. Great warranty. We wish we had bought this mattress sooner! Search on this forum for bedinabox and you should see more reviews. That's how we found out about it.
