Nice bed, directions need improving
Size: Twin, Style: Leah, Size: Twin, Style: Leah
The assembly should have been so simple. But because of the directions using letters instead of numbers and the product pieces being identified with numbers not letters, it yielded confusion. What should have taken 30 minutes ended up taking over an hour with more head scratching than there should have been. Overall great piece. The box was severely damaged upon arrival and was taped up poorly. A few pieces fell out of the big hole in the box and got knicked up when bringing inside thebhouse...not worth returning over, but still unfortunate for a nice bed. All said, the bed looks nice and feels sturdy for my toddler.

Solid Frame – Worth It, Just Be Patient with Assembly
Size: Full, Style: Kai
Long Review:
Surprisingly solid bed frame—well-designed and very sturdy. The packaging was slightly damaged during shipping, but luckily the frame itself was untouched. The included ratchet tool was a lifesaver; tightening all those bolts gets tiring fast after the fourth or fifth piece.
The instructions could use improvement. The printed manual uses letters for parts, while the frame itself uses numbers—this mismatch makes it a bit confusing at times. The numbered stickers are helpful, but without labels on the parts, you’ll have to rely on grouping them visually and cross-checking with the paper guide.
Assembly doesn’t require much brainpower, but the most frustrating step was attaching the backboard. I recommend leaving all the bolts loose until everything is aligned; trying to force the bamboo headboard into place can lead to misalignment or even damage.
TL;DR:
Great bed frame, sturdy and simple to assemble. The ratchet tool is super helpful. Instructions are a bit confusing—but better than IKEA's. You got this!!

Looks great, not quite easy to assembly.
Size: King, Style: Leah
Mostly easy to put together. Instructions and it's labeling of parts was a bit confusing, but if you pay attention to orientation of parts and where the holes are at in the photo, you'll get it.
We've been sleeping on it for 2 months now. No problems at all. Seems very sturdy and no creaking or squeaking. One bolt inset was stripped and wouldn't take the bolt (left middle crossmember) but with at least 1 in it, it's working fine. It's not load bearing really so it doesn't matter.

Very nice!
Size: Twin, Style: Leah
This bed frame is fantastic, and was a lot easier to put together than some of the reviews would have you believe. The instructions were good, and the pieces of the bed were labeled with stickers to make it easy. It even came with a little ratcheting Allen wrench that made things faster.
The bed doesn't wobble to creak, it looks nice, and it was affordable. I am very happy with it and I think that you will be too

Decent price. Needs improvement.
Size: Queen, Style: Kai, Size: Queen, Style: Kai
This frame was a good price. And for that price it was good enough, but not perfect.
The directions do not match the stickers on the pieces. But if you match up the stickers and ignore the directions, its not hard to assemble.
The metal slats are to far apart to prevent mattress sagging. They are also very smooth an the mattress would easily side out of place.
The headboard looks great. The metal is solid.
In order to fix the mattress sagging and sliding, I opted to make some cheap bunkie boards. I got some thin utility board from the local hardware store. It was damaged and only cost 5$.
Cut 77" by 12" was the right size. Drilled holes and zip tied to the metal slats. Random holes for ventilation.
It seems better now, only time will tell. They should update the directions and add more slats.
