Slightly disappointed in the metal bars that hold up the mattress. I chose the metal because my daughters last loft bed had the wood slats and broke easily from the slightest movement. (She wasn’t even close to the maximum weight limit) The bed went together easily but when my daughter got on it, the metal bars bowed more than I’d like. (She’s not even 100 pounds) I thought the metal would be more sturdy. there is also quite a bit of shaking when she is on it. It needs some more bracing or something. If it wasn’t for her loving it, I’d give it fewer stars.
