No complaints. I was able to manage this in a cramped space by myself. Its metal, so it should be sturdy for years to come! No problem with the cover, either. The instructions were literally 2 pictures. I also bought this as an open box item.. Antoinette. New Milford, CT. Sat Jul 25 2026

This was so easy to assemble. I'm a lady in my 70s. I had it together by myself in 43 minutes after unboxing. I really appreciate the bamboo product. It's very pretty, I was sorry to hide it with the cover. Goldie. Wytheville Va. Thu Aug 13 2026

Absolutely perfect and just what I needed. My staircase to the second floor could not take a king or a queen boxspring upstairs. My husband had to literally break both to get them up onto the second floor. It was horrible aa overtime the boxspring just became lopsided . The double split was so easy to manuver to the second floor and fit into my platform canopy bed frame. I definitely sleep uninterrupted.. Natasha. Elizabeth, NJ. Sun Aug 09 2026
