Having had this bed for 6 weeks I would now alter my review. My son is a slim average height teen, but the metal struts that support the mattress have really bent already. I bend them back to shape often but a day later they have sagged again. May be suitable for a younger child, but very squeaky and needs regular adjusting and tightening of screws. 

Easy and quick to put up. Have had it up a week and have had to tighten the screws twice but this maybe because they weren’t tight enough to start off with.
