This has been perfect for our two boys. We were graduating from a toddler bed to our big big bed for our 4 yo. This is a very sturdy bed. The slats are a bit wide apart and the mattress people said we may want to buy a board to put between the mattress and slats to keep the mattress from sagging.  Only needed two people a couple of times. Note: put the mattress in before putting the ladder on - lol we learned the hard way.  All in all a great purchase- I would highly recommend.
