TLDR; Bed quality is OK but not great. With well-written instructions assembling it would be a piece of cake, but I wasted about 2 hours because of instruction quality.Hint. Their website (ztozz.com) does have somewhat better instructions, but I discovered them only while writing this review. Not that parts included are NOT LABELED, which makes it harder to follow the instructions (some manufactures place stickers with part numbers/letters on the parts themselves to help customers assemble their products).The company. ZTOZZ claims to be a US-based company with a warehouse in Florida. You can order from their website, or from Amazon. "1A Trade" seller is the official seller. However the sticker attached to the bed indicates that it was manufactured by "Anhui Willsoon Furniture" in China (see the picture).The first issue I had assembling this bed was that I was unable to find headboard legs (3 large pieces). I called TZOZZ customer service earlier today (Saturday), and was immediately connected with a representative (GOOD :) ). The representative looked up my bed model by Amazon order number, and then immediately asked if missing pieces are headboard legs. Apparently the legs are HIDDEN inside of the headboard. I can conclude that this is a common issue, but instructions that came with the product do not mention this, and TZOZZ did not try to inform me about this issue upon purchase.The second issue that I had was that I used 50mm bolts to fasten bed sides to headboard legs (my bad). As a result at some point I ran out of 50mm bolts, and the package does not include any spare bolts. I hoped to get a replacement in Home Depot but I was unable to: bolts included use a metric system, and they are not compatible with bolts that Home Depot had in stock (5/16" bolts look the same, but they are not). The bottom line is: DO NOT LOOSE ANY BOLTS.The third issue was with connecting parts C1 with a1 (and C2 with a2) -- these are two parts making bed sides. I had to apply force to get them together properly (build quality issue). This damaged the hex wrench which came with the product, so I finished it with the help of a power tool (drill with a hex head), and had to get a hex wrench from Home Depot to finish the assembly.The forth issue was with mounting feet to the rare board. Instructions tell to use 50mm bolts, but they seemed too long, and when I measured the depth of the hole I realized that 35mm bolts would be a better fit. This bed came with exactly two 35mm bolts, but instructions tell to use them in another place where they can be safely swapped with 50mm bolts. DO NOT FORCE BOLTS TO FASTEN FEET TO THE RARE BOARD. Use 35mm bolts instead.The fifth issue is that mounting of headboard to legs can potentially damage wood if over-tightend (see the picture). I personally decided to add washers.The sixth issue is mounting the led lights. It is easy to do, but it is not clear how to hide the cable at the headboard (see the picture).The seventh issue is that instructions do not tell how to position slats. If this is the first bed you assemble: slats need to be bent upward! Slats do not look very solid, but should be good enough.Finally, when I was looking at the product picture I had a feeling that the bed sides are curved at the bottom (wider at the top and narrower at the bottom). This is an optical illusion: sides are straight, but led lights make the top part brighter which causes this effect.The material that cover the headboard and sides looks like a genuine leather (I could be wrong).To the company: respect your customers, spend a few bucks to write proper instructions.
