-pieces are clearly marked with which side faces upwards and which order they are supposed to be put together
-instructions are visual with the only text being used for the numbered parts, simple enough to understand and really only needed to take a glance for each step since they also included a small pictorial of where the part was in comparison to the finished frame. Could see it being difficult for people that like their instructions read to them or if the label stickers on the parts are skewed or misplaced, but everything was clearly laid out with no issues and pieces were as marked
-pieces fit well together with no issues, all holes matched and bolts were the correct size
-included all tools needed including a handy little ratchet to use instead of the Allan wrench, did make it a good deal easier
-packaging had very little waste. The metal bars and pieces fit snuggly into the box and we're bound together with zip ties, 2 hand sized blocks of foam that padded both ends were left in plastic bags to prevent any mess, the fitted outer sheet was in its own bag, and the bolts and other pieces (including labelled extra pieces) came in a clearly marked cardboard package with a clear plastic front, the instructions were printed on paper. Very little waste and cleanup
-stickers stuck to the metal a bit but will come off
-took about 30-45 minutes to assemble for one person, took two people to get it in place after being assembled but one strong person could do so if they have the space to work with
-the outer fabric fits perfectly and works like a fitted sheet, no issues getting the fabric on with two people working on it but it could be a struggle alone
-fit in place perfectly, no issues with creaking once placed correctly on the bedframe, works as intended!
Was honestly ready for an afternoon of assembly and got it done way more quickly, would recommend
Before I ordered this, I read through all of the questions and answers which took a couple of hours. So glad that I did as several customers mentioned the cover and problems putting it on. It is a very tight fit but if I can do it at my age, anyone can do it. A suggestion to the manufacturer would be to add perhaps 1/4 to 1/2 inch more fabric and it would not be so difficult to place over the box spring.
I also watched the video twice before I ordered this and that was easy to follow. Four of the pieces were labeled with a yellow sticky that said 'up' which was most useful. My other suggestion would be to label all of the pieces with 'A, B, C, D etc. which would have decreased my assembly time by at least one hour. I did go back and watch the video again while I was assembling.
Total time for me to get the pieces in the right order, double-check the placement, tightening of the hardware, etc, was 4 hours. After I got the box spring assembled, I went around each piece and put pressure on each one, to make sure things were as tight as I could get them. I am visually impaired so perhaps that contributed to the amount of time it took me to assemble it.
At my age, I am thinking that perhaps I should have had someone make sure I had everything tightened well. If anything loosens up over time, will have someone help tighten it for me.
All in all, so far and so good. The mattress I have on top is really heavy and as I stated previously, the box spring has no squeaks and appears to be most durable. In other words, no movement of the box spring.
Update to follow if anything should occur.
Edit on 26 MAR 2019... Have been using this for 17 months now... No squeaks, absolutely zero problems! Still as satisfied as the day i first reviewed this in October of 2017. And, my recommendation is still that I highly recommend this box spring.
Update on 10 OCT 2019.... The 2 year anniversary of this box spring and once again there are no squeaks and zero problems. Still highly recommend this box spring~
Update as of 30 JAN 2021...Absolutely still in perfect condition. Was going to increase the star rating to 5 but don't dare to change it. Truly outstanding and most highly recommend this item for everyone that wants a sturdy and long-lasting box spring. Could not be any more pleased with a product...
Most highly recommend...
I believe the item I received had some minor defects in one section. Pieces 3 and 4 did not properly line up with their intended screw holes. I had to call in my wife for back up and together we huffed and puffed and almost blew the house down with all of our yelling out of frustration. We had to have one person hold the section into place while the other hammered it in. It took way longer to assemble than it should have because of this.
Another issue, which isn’t a big deal for us as this is for our guest bedroom, but something that may be good to know if you plan on purchasing it… we ordered a queen and it is smaller than the queen mattress that sits on top of it.
