I have a double bed available that I bought 3 years ago from Jysk. It has had a bedbug cover on it since the day I brought it home.

There is a “floating” bedframe that come with it. You don’t need a box spring for it. The bedframe has chew marks on it from my puppy and one of the sides is cracked but it still works perfectly fine !

Let me know if you’re interested and I can send you some photos
