My boys both have an FLEXA bed, super strong stable and durable. but they wanted to have a tent on the top bed, There are a lot of tents made by IKEA but obvioules these don't fit. so I've designed this adapter. you will need 6 of these for one tent/bed. one is build up with 3 parts, left, right and middel. I didn't need to glue as it snapped together perfectly.
