I bought this daybed for my 12 year old daughter. She wanted to size down to allow more space in her room. She hasn’t stopped thanking me and telling me how much she loves her new bed. I purchased a twin sized mattress 8.5” thickness for top and trundle (it fits perfectly). I assembled this bed all on my own. It took a couple of hours. This bed is very chic and beautiful. It looks even better in person! I would highly recommend this bed!!
