This is a very good solid hi riser bed. We looked for one to use in our office, which is also a partial guest space. The hi-riser solution is terrific, because it provides us a solid double twin bed, with regular mattresses (purchased separately), and takes up minimal space - much less than a daybed or sofa bed - and so much more comfortable to our guests!
Only problem was the hardship putting this together, as it required screwing in about 30 screws in main bed frame, each with provided tiny tools. I worked on this for 2 days manually and gave up (i'm a woman, and not very handy, but usually manage putting basic furniture together), hired a handyman who was able to do it better with power tools and stronger muscles than me ;)
Great Product and would highly recommend... just make sure you help screwing it together!
