Easy assembly and smartly shipped in a box. Pros of a Hunlostten Bed Frame Low profile beds are close to the floor and look great aesthetically in a simple, minimalistic bedroom. It also works well if you have a small bedroom, but want to give it the illusion of being spacious. However, low profile bed frames often come with little to no space for storage under the bed. Headboard and Footboard no included! Screws cannot be tightened by hand. Use the included hex wrench for a secure and sturdy assembly! The screw package includes spare screws and nuts, so it's normal to have extras after installation. Bed Frame Specialist What makes our products unique?

Better Mouse Trap for Sleep Number Base & Frame Units
Size: Twin XL Style: 12 Inch
Was looking for a lower priced option for a Sleep Number frame and base unit. This frame, a bucky board and I save hundreds of dollars from what Sleep Number wanted. It works.

Get what you pay for
Size: King Style: 12 Inch
Overall for the price it’s great, easy to assemble for the most part, and clear instructions. I have only two problems with it. First while putting it together a few screw holes did not line up. one I wasn’t even able to get in at all, two others we were able to manhandle and get them in. Second is the mattress does slide around, but I would recommend purchasing mattress grippers solves the problem easy. Overall services it’s purpose, but had some minor mishaps ... show more

Doesn’t shake or squeak
Size: Queen Style: 12 Inch
Bought this frame as a space saving option and didn’t expect much. Mostly just bought it to keep the mattress off the floor. We have had it about 6 months and have been pleasantly surprised. It is very sturdy and doesn’t wobble or shift at all. We have another cheap metal bed frame that we keep having to tighten the screws - not this one! Even with a toddler climbing and roughhousing on it, it has stayed sturdy and tight. No loose screws or squeaking. It was also easy to put together; I did it by myself in about 20 minutes. ... show more

Do Not Buy
Do not buy. Slats don’t align and bed is unusable. Spent over an hour trying to figure it out. Bed frame measures 52” on one side and 55” on the other (width).
