Love this daybed. I put an 8” foam mattress on top. Haven’t put a mattress on the trundle yet. My husband put this together in 2 hours.  Overall, it is beautiful and I love the velvet fabric and the light blue color. The picture is true to the actual color. If you run it against the grain, the blue is significantly darker. Very comfortable and fits perfectly in my office. My 8 year old like to hang out on it while I’m working in the office. They have been warned not to jump on it. The mattress is held up by slats which my husband (who is an engineer) says will only be stable when weight is distributed over the mattress. Therefore, no plopping onto the mattress and no jumping. It is perfect for sleeping and lounging but this is a little deep for a sofa.
