    Great bed frame!This was everything I wanted in a bed frame. It was delivered promptly. Box was light enough that I could slide it down the hallway and into my bedroom. I am a 64 year old woman and set it up by myself. Once I got the braces in the corners figured out, the rest was a breeze. I love the height and sturdiness. No box spring needed. I would buy this again.

    Happy with Zinus!This is about my 8th Zinus purchase, mattress and base. Really nothing bad to say. It’s a bed in a box. Amazing technology and no one believes it came in a box. The platform is awesome and it’s plenty tall ! So great! Get one!

    PerfectThis is perfect for me. When I ordered a new mattress I decided to get a new frame also. Our old one had a floor clearance of about 6 inches. With my health issues it was difficult to get up and down. Now I just roll on and slide off.Assembly was very easy. we bought the headboard to go with it. My husband had to drill a couple new holes in the headboard but that only took an extra five minutes.We did have to adapt to the height. Laying in bed the ceiling appeared very close for a few days.

    Do not use with a box springI love the height and storage my bed had now. I already owned a box spring and didn’t want to get rid of it so i put it on top of the baseNo my bed is super highBut i love it

  5. Cyni

    Still Up for debate.We just purchased the 18 in Casey in Dec. Can’t say much about it yet. It’s too so. But as to-date it seems okay. Not squeaky at all…

    Best cheap bed base available, period.This thing is easy to assemble and is great quality for the price. I would reccomend choosing the tall base though to give you more storage space.

  7. Kindle Customer

    one two three and it is put togetheris exactly as noted in the details. Added a head board and it looks great. Would definitely recommend.

    Love itWe had an older queen bed frame with only about 7″ underbed clearance. This frame provides not only 17″ storage, but replaces the need for a boxspring. With the 18″ headboard/footboard brackets, we could easily attach our 38yo wooden headboard to the frame. We plan to replace our whole bedroom suite in the next couple years. With our 13″ hybrid mattress, its a wonderful cost effective solution. We had purchased the same mattress and frame, in a full size, for our daughters college apartment and she mentioned it more comfortable then her home bed 🙂 My husband is a bigger man and after only one night, he could feel the difference on his back
