Zinus 9 Inch Metal Box Spring with Wood Slats Mattress Foundation

Mallory: I didn't know a king size bed didn't have a hump in the middle. This frame is very sturdy. Nice and flat. It's been in use for 4-5 months with no squeaks or wobbles

Elizabeth: I absolutely love this product. I bought the box spring for my own king bed a few years ago and now bought this one for our guest bed. The frames are easy to put together and are very strong and sturdy. The even send you a cool little tool worth hanging onto and extra nuts and bolts. This is a great company!

Nobody of Consequence: The parts are clearly labeled to make assembly fool proof. You connect joints labeled 1 with their peer joint also lableld 1. Repeat. The picture guide is outstanding. My only hiccup was a screw did not want to go in. I found that the sticker labeling the part had loosened and was covering part of the female connection. They provide spare screws, a hex wrench and a ratchet hex wrench. A step up wou;ld have been to deliver a ratcheting torgue wrench to help ensure customers do not over tighten screws.

The cover that covers the frame even has a tag on the corner that helps you orient the cover over the width/length dimensions. Although a small detail, that was extremely helpful (think of a fitted mattress pad or fitted sheet - guessing which sheet corner matches to which matrress corner!).

The wood slats have a strip of velcro stapled to them and the bed frame has a matching strip, The velcro on the slats has gaps between slats to help space them out.

The box tha arrived and was pretty beat up, I think every seam had additional tape. It was clear the box had been abused. But, it didn't really matter. The packaged goods made good use of the metal frame to protect...

Karen MKaren M: I purchased the low profile 4 in model. This foundation is high quality, easy to assemble, and sturdy. It does not squeak or sag at all.
Tips on assembly: Everything is numbered on each end and you just match up the numbers. The edge pieces fit together like tongue and groove that are held permanently with two screws. Do not bother trying to use the tiny ratchet provided. It breaks almost immediately. Instead use the Allen wrench provided. (It will save you a lot of headache). Put all the screws in as far as you can with your fingers and then the last turn with the Allen wrench is a lot easier. Be careful when laying out the slats on the velcro. Make sure they're pressed down tight when you're done. Lay the cover out on the floor and set the frame on top of it pull it up around each side and zip it. Find the tag that says TOP and make sure it's at the head because the cover only goes one way. It took me 45 minutes to put together the first one and 20 minutes to put together the second one. Great product!

Amazon Customer: Bed frame was easy to put together. Just follow instructions. The cover didn't seem to fit right but once remembered that king size is longer than wider the cover went on really easy....check the dimensions.

Neil: I have purchased items made by Zinus, in the past and have been extremely happy with them. I found this King size boxspring to be well made and designed. It was a snap to put together and it even came with it's own ratchet tool!
The boxspring is solid and I would highly recommend to anyone.

C and C: I bought this for one reason only, my existing box spring was so loud, getting out of bed even woke up the neighbor's cat! It was super easy to install, the wood slats are less than 3 inches apart, and held in place by velcro. And, it is super solid and there is absolutely no noise, at all! Excellent product, super fast delivery! My first from Zinus, not my last.
