Flimsy
Size: Full, Color: Walnut
Design which reduces size of box it's needed to ship in results in a frame that doesn't feel durable in the slightest. Sub par compared to other frames at similar price point.

Outstanding affordable bed frame
Size: Twin, Style: Kai, Size: Twin, Style: Kai
Outstanding bed! Just the right size. Sturdy! Easy to assemble and looks great, too. I had some issues like other reviewers. Mattress slid so I put a layer of foam down between the frame and mattress. All good now! The frame’s too low to the floor for me so I added a thick foam topper so I’m higher up. No issues with slats falling out or anything getting loose over time. I had some difficulty assembling the frame as described but that’s a “me” problem. Got everything correct after a couple tries. The multiple attempts caused no damage. The wood slats took some rough handling during assembly due to them fitting in tight. Assembled fine as a single person with no help. Highly recommend! Especially for the price.
