    • Easy to put together, and exact as description indicates
Color: White Size: Queen Style: 7.5 Inch Box Spring
Queen size.. I bought this a few days ago to be the platform base for my new foam mattress. I don't write reviews, but after i put this together and laid it on my bed frame, i just had to. Packaging: UPS shipped and it had some dings and tears, but the internal edge padding and box tape kept it together. I was mildly concerned but figured id open it before i got too excited. Opened Package: Instructions, tools, and bolts in a nice easy open/close plastic storage bag. The box ends were heavily padded with foam inserts to protect the rails and wood. The rails were tied and wrapped in a plastic glove that protected them and was very easy to pull off. All nice and secure. Instructions: I wondered if the writers worked for Apple or Google. The several steps had detailed pictures. were very easy to read and nicely laid out. (the labels in the instructions were exact to the labels on the rails and bolts).. Tools: 12 bolts, 4 spares, an allen wrench, and believe it or not... a small simple allen ratchet tool.. Seriously? Nice touch. All tools were in a fitted package and labeled so you dont loose anything. Build: Three rails attached to 2 ends to create the rectangle platform. Every end attachment had a sticker, labeled 1, 2, 3, .. 6. Screw hole on rail 1 met with screw hole 1 on end piece... and so on.. easy.. The bolts were thick and were easy to hand twist with large ridged edge. I used my fingers to insert the bolt and screw in every one (12 total). What that means is that the steel was machined perfectly. Every hole was lined up and matched every cut out and each bolt fastened easily. No nuts required. There were 2 sets of wooded slats that were connected to each other with velcro ties, the bed rails edges had velcro surface the entire length of the rail, which means the wooden slats connected to each other and stayed put on the rail. It took me less than 5 min to attach them. It has a ledge for all the wood slats to sit on AND had velcro to keep it in place. Then i put the frame on its side and put the cover on and zipped it up. Fit like a glove. small wonders.. i didnt expect this actually, so i have to give credit where credit is due.. I'll update this after its used.. ... show more

    • Strong and we say to assemble with closely spaced slats
Color: White Size: Queen Style: 7.5 Inch Box Spring
Looking for a box spring to on with a new mattress but didn't want to pay the crazy prices on suites like Purple. Most modern mattresses require the slats to be less than three inches or so and many metal box spring slats are too far apart unlike this Zinus model. The delivery box is pretty heavy and tall with everything being fitted together neatly in the box with no shipping damage even though it was unwieldy for the UPS driver to deliver it.Assembly is easy as everything is numbered and the side and middle rails fit together perfectly and I was able to put it together single handed. The holes aligned perfectly so screwing it together was easy especially as there was a basic ratcheting wrench included along with a conventional hexagonal wrench which I did not need to use. It is easier to fit the slats with two people and they attach to the Velcro strips on the rails with ease. The cover fits well and was we say to put on as it was neither too tight nor too loose and seems well made. The zip on the cover did not give by us any problem Altogether this is a very nice product with the proviso that it must fit your bed frame of course. One bed we have is too big for the box spring to fit by an inch or two so measure carefully! ... show more

    • Highest quality product I've purchased on Amazon.
Color: White Size: King Style: 4 Inch Box Spring
Sounds crazy but it is. Materials are top notch. Instructions were super clear and they even provided a handy Allen wrench ratchet tool to make things easier. We bought an Amazon basics platform before this and had to return it because the dimensions were slightly off.

    • Excellent metal box spring by Zinus
Color: White Size: Queen Style: 4 Inch Box Spring
Very well made, great price for materials. The instructions are really easy to follow and numbered. came with all needed materials to assemble. The wood slats are Velcro, so they stay put. Really happy with product and would definitely recommend.

    • Heavy-weight foundation that provides a good value (especially when shipped using Amazon Prime) with an accurate description
Color: White Size: Queen Style: 7.5 Inch Box Spring
Positives: I have had this foundation for over a month and have been using it nightly. It was a very good replacement for my box springs, which creaked from the first day I got it. Now, with this foundation, there is no creaking and no noise when I roll around trying to get comfortable, which is an improvement. Since I am a bigger guy, this impressed me. So the engineering and manufacturing were done well. The price provided a good value given that with Amazon Prime shipping, this 50 lb. monster was delivered to my door. (But the shipper bang up the box pretty bad.) The packing did a good job protecting the foundation against a poor delivery. Although the box was beat up badly, the contents were in perfect shape. Nothing was damaged. Assembly took some time, but no extra tools were required. The instructions were well written. And the manufacturer provides extra parts, just in case. So if you follow the instructions exactly, one person can assemble this in less than 45 minutes. I would guess that would go a lot faster with two people. The cover took the longest. Putting it on so it does not rip with one person is a real challenge because the foundation, once assembled, is heavy and ungainly. But once on, the whole thing is well protected against dust and dirt. The design was innovative. The manufacturer uses velco to keep the wooden slates from moving once installed. As a result, the whole unit, once assembled, is very sturdy and sound. Negatives: This thing is heavy and very ungainly for only one person. The box weighs over 50 lbs. and is long. Getting up stairs with one person is challenging, but with two there should be no problems (unless you on a 5-story walk up, then good luck). Once assembled, the weight makes it hard to move around until it is on the frame. Overall, this did not get a 5-star review because of the weight. Using all-steel construction for the frame means it weighs a lot, but that is what makes is sturdy and solid. And this is its only downfall. So, I would recommend this foundation as a good value and as being well represented by the text and images listed on Amazon. ... show more
