Wish I wouldve know. Ahead of time to buy a spring mattress. Saw where others said that they bought a foam one so I followed suit. The warning labels say to use a spring mattress to avoid injury. Were going to have to modify as others have suggested by putting plywood down, but its a pain since were an hour from a hardware store. Otherwise it seems sturdy and was easy enough to put together. Hoping it will be a good height for our 3 4 yr olds. Will update after weve had it for a while.
Update: this is still holding up well after 2 years. You do need to tighten the bolts periodically and it does wiggle a bit more than when we first assembled it. Will be adding the 3rd bunk this year to accommodate our 3 yo Much better than expected
