  1. Le

    Headline: Drunk 5’4″ Single Woman Assembles King Bed Alone And Nothing BrokeI ordered this because it looked and claimed to be easy to assemble. I live alone on the third floor of a big apartment complex, the kind where humans live in their little cubby holes in a row of cubbies. I wanted to eliminate the hauling I’d have to do as much as possible, and was delighted to find some poor UPS guy had delivered the 7 ft long box directly to my door. I was doubly-delighted because I was already a bottle of wine in that evening and I’m one of those cursed with the propensity to break things, sober or not.There are pictures of 2 men lifting all over the box, clearly indicating what was expected to do the job, so of course I grabbed the box and wrestled it into my apartment all by mahself, because #feminism or whatever.I should preface the remainder of this review by explaining that I may be all of 5’4″ on a good day, but I’m also a competitive bodybuilder, so I can lift things and stuff, but once the bed was indoors, things got easier. So if you’re all of 5’4″ and not a bodybuilder, that first part may be hard, but I believe in you.The instructions were only two pages, but I wasn’t upset. I mean, lately I’ve seen the furniture directions where the paper is one page with 100 different pieces depicted, with all the arrows pointing to them all going together, so the instructions are literally just, “Take all the parts and put them together, then done.” Those make me want to hurt someone.But these instructions made all the sense. You take the big pieces, hook them into each other, and then you already have the base done, boom. They even supply a super cute little rubber mallet to make the process easier. Of course, I didn’t see that until I had man-handled all the pieces into place and was sweating out all the wine.Then you drop the slats into place, easy peasy.But then, this slip cover…. Look, my one complaint is that it came with a tag that explained which way was forward, top, etc. on the slip cover, but the thing had fallen off and was sitting sadly in my hand while I stared blankly at the slip cover, not knowing which was was up, down, or sideways.So I had another sip (swig, chug…) of wine and began wrestling that damn thing on.Now I know from experience and can warn you that if the slipcover fitting feels impossible and makes you curse the fact that society thinks that mattresses on floors is unacceptable for functioning adults, you are probably putting it on wrong. I wrestled with it in 3 different directions until the last time, it finally seemed to fit right into place, and I realized I had it right finally.Hint: The zipper zips on top. Yeah, didn’t realize that the first 2 times.The legs go on way easier than expected, right through pre-cut holes in the slip cover.And then BAM. I was suddenly an adult again and no longer sleeping on the floor.So if you’re wondering if this will be as easy as it claims and work for you, the answer is probably yes. I might recommend the wine to go with the experience. Particularly, a good cabernet will help get the job done.Men not required.

    Very impressedYes, this was easy to put together. My 11 year old helped me (I’m injured) and we did it in like 10 mins. Looks really good, perfect for said child and his room. Not too fussy, not too plain, but just right. Good construction, solid materials, easy to put together. I think I got the open box model and yes the box was open but everything was included. Would definitely recommend for an older kid since it’s a long way down if they fall off, unless you have a thin mattress.

  3. Jessica

    Totally worth itTaylor Easy to assemble, my 13-year-old and his uncle put it together. It’s sturdy and very chic. I think it’s totally worth the price and then some. The bed for my 13 year-old son he’s a big boy. I’m not sure how long he’ll use it for. But again the price and quality you can beat.

    Super Easy and looks great!The product is exactly as it says in the description. I put the frame together all by myself, with no help. We did opt to remove the legs because with our 14” mattress, it was much taller than we’re used to. It did look really nice with the legs and if we had a thinner mattress might have kept them on. Highly recommend this bed frame!

    Awesome bed frame, but has developed a small squeak overtimeThe media could not be loaded.

     We’ve had this California king bed frame for a few months now. We decided to buy this because I couldn’t make my mind up on a bedroom suite. Assembly was very easy. Everything was labeled properly. Its way sturdier than other metal frames i had. I love that there is a cover to go around the base of the frame to hide the boring metal. Even the legs seem to be made very well. On the California King there are a lot of legs, 9 I think, so it holds up really well. Overall this frame has been amazing. The ONLY complaint is over time it developed a small squeak. You can hear it in the video. I’m sure if I put some oil on it will probably go away. I would definitely recommend it to my friends.

  7. Amazon Customer

    Assembled Quickly!My husband assembled this by himself really easily. He was super happy with it and the fact it came with a mallet. It has held up well and supports our mattress well.

  9. Anna

    One month of useStill working as expected – no creaks, very sturdy. It was very easy to assemble and looks great in the bedroom. I was looking for no headboard frame that wasn’t metal and this was the perfect choice for my price point. Will buy another for our guest room.
