Unstable and creaks like hell. This bed has been put together correctly and as per the instructions yet it creaks a lot and is as unstable as anything if anyone moves the slightest bit on either bunk it creaks and wobbles. The listing also says that it supports up to 150kg per bunk, now both my brother and I are nowhere near 150kg yet the metal slats are bending significantly by the ladder. The assembly was awful, I bought it under the impression that it uses bolts like a normal high quality (and rather expensive) bed would, but instead got a cheap, very badly made bed with plastic to stop it falling apart. Not good and very misleading. The parts don't fit together well as parts such as the ladder are a completely different size than the holder for it. The only positive thing is that it is comfier than my old bed, but that may be due to a new mattress. No I do not recommend this bed and I highly advise that you stay way clear of it

Great easy to Assemble my boys loved it
