Currently waiting for the seller to respond to my request for that instructions. The box arrived okay, the bed frame boards look good, but some of the mattress support slats look unstable with cracks or poor craftsmanship.I will update this review once I get instructions & am able to build it.Edited: The bed has been built. The seller sent over instructions digitally. It was easy to follow. Just get your slats spacing planned before screwing them down. Slats that didn't look sturdy were put between stronger boards in an area where not much weight was expected. My kid loves the slide but it is steep. We've added a block under it to give it a bit of rise, so he is less afraid to go down.It's definitely not built for jumping on but it is sturdy. Secondly go for a mattress closer to 6" thickness.Updated 2024: this bed has really lasted over the test of time. We added a thin wood board (similar to ply but solid wood) the full length of the bed. This has helped with friends coming and roudy play. We raised the beds on wood and secured it to the wall as it was wobbly the bigger he got. He's 7 now and the under bed space is still the coolest place to be.
