Good
Pretty easy to setup. The directions were easy to follow I setup in less than an hour. It’s kind of flimsy when moving it around but holds up well for sleep. Not squeaky at all.

Wooden slats not sturdy enough.
The bed frame looks nice, but the holes were not all aligned well, and with a bit of wrangling we were able to get it assembled with two people in about 45 minutes. The box was small, and the side rails are actually two pieces. Be careful because I pinched my hand pretty good when trying to align them after everything had been screwed together. The slats that go under the mattress are very thin and I'm concerned that they will break eventually. I think the company could have used better wood for the slats and still charged the same price. It's so hard to read through a ton of reviews to decide which bed frame to buy. This one is OK, but I see myself having to purchase wood in the future to replace the slats. It's long enough for a grown young man of 6'1" to sleep on it, but if my kids were younger and prone to jumping on beds, I'm sure it would break.

Stains on the same frames don’t match
I’m quite frustrated with this product. I ordered two natural wood frames for my boys bedroom. The first frame arrived, and it was definitely natural wood. The second frame arrived and it had a yellow stain to it. So I returned it and the company sent me a new frame. Also yellow. So I returned that one and ordered yet another natural wood frame. You guessed it. It arrived with the yellow stain as well. I’m not sure what it’ll take to receive an actual natural wood frame but I sure am frustrated with all of these returns. Meanwhile, only one of my boys has a had a bed frame for the past 18 days. 😣🙄
