  1. Ken

    Excellent valueThis bed frame is very sturdy and well built. It takes very little time to assemble. Excellent support of my mattress.

  2. Rebecca Miller

    Great platform bedIt was easy to assemble. We needed something low profile for my aging mom. It fits the bill. Now we don’t have to worry about her climbing in and out of a high bed.

  3. Amazon Customer

    Quick and easy to put togetherI had purchased another brand 18 inch that was way to tall with the 14 inch mattress it took quite a while to put together but this one was like 5 minutes and looks so much nicer with the cover and wood legs

  4. Ani

    Incredibly easy to put together, took a few minutes with no help!Literally couldn’t have been easier to put together. I was worried it wouldn’t be sturdy or be really squeaky but its not at all!

  5. Forrest Yoder

    Should have bought this way sooner than I did.It arrived really quick. It was super easy to assemble. It came with a little hammer to make sure your joints were connected well, but I found that I could use my heel with no shoes on and it was easier to get it flush that way. Didn’t take much pressure at all.All that aside, when it is assembled with the mattress thickness I am a very comfortable height off the floor. I’d say way more comfortable than traditional box spring and mattress beds. The frame is super sturdy and doesn’t creek. I don’t feel any motion from the bed when I roll around in my sleep.The only negative thing I have is that the shippers dropped it off outside our front door before we opened at my place of work which is where I have most things shipped because I’d be there to receive it. But no one stole it, so everything worked out.Overall – great value, definitely a good choice!

    Great with.one issueThis is a substantial and strong box spring, albeit without the spring. It was easy to put together and took me less than 30 minutes to put together. Very pleased with the frame except for the cover; flimsy and light. We own another Zinnus and within two years the cover developed a couple of tears. By way of reference our Energizer Bunny batteries have long since died, so the frame cover should have lasted longer.

  7. Margaret Eastin

    So far, so great, especially for the priceSeemingly sturdy metal frame, satisfactory aesthetic appeal for the price. Very easy to put together; I did so by myself. As a female who isn’t very mechanically skilled, this was invaluable. The box it came in is heavy but can be moved by yourself with care. The individual pieces are very easy to move by yourself. Seems to be great quality for the price so far. Comes with a rubber mallet, which I relied on because I didn’t have one! Only complaints are: a) in some places the metal wasn’t filed down enough to fit together first try, but this was remedied with the mallet, and b) some markings on the feet, but those are under the bed anyway so it doesn’t matter much. I think metal bed frames are ugly so I loved this bed for the upholstered cover, which is unfortunately spot clean only, but hey at least I can clean it! I hope that the bed frame isn’t squeaky and stands up to moves – will update my review if the frame doesn’t stand the test of time within reason. The upholstered cover was very snug so take care not to snag it on anything.

  8. Joe Benson

    Great base for our memory foam mattressWe were able to assemble this base and slide it inside our mission-style wood bed frame. It’s now a great base for our new memory foam mattress.

  9. Cheryl Kincanon

    Love it!!!This was so easy to assemble and looks great! There’s no squeaking or noises at all. The only negative thing I have is that you can’t connect a headboard to it but I’ll rig it somehow.. glad I purchased this!

  10. Yen

    Good affordable bed frameI bought this because i needed a nice temporary bed frame that didn’t break my bank. It was super easy to assemble, i finished it within an hour. I have carpeted floors and it’s very sturdy and not squeaky. I also really loved the wooden legs. For the set price it’s a pretty decent bed and the ship was very quick.
