Review on ZIYOO Twin Box Spring: Premium Metal Box Springs with 7 Inch 🛏️ Mattress Foundation – Easy Assembly, Heavy Duty Support up to 2000lbs, No Noise by Angela Johnson

This was a lifesaver for the queen bed we put in the attic after we moved in. There's a little hatch where we put the details of the bed and thing - but the spring block - forget it. We found this and thought it was worth a try and it worked great. The box was easily moved to the attic. Approx. 30 minutes to set up and bingo - fully functional pen box. The case is good too. You would never guess that this is a custom pen box. The only problem was assembly - the pieces have tabs that don't line up as easily as the assembly instructions make it seem. But with the help of a heavy pair of pliers I was able to align everything and put it together. A great solution when space is limited.
