ZinusCompack Fabric Covered Wood Slats, Bunkie Board, Box Spring Replacement, Twin

This Bunky Board setup is a total game changer. I have a metal box spring, and even with the cover it came with, my mattress used to sink between the gaps — especially at the foot of the bed. Anytime someone sat there, it would dip down and stay that way unless I went over and fixed it, which was super annoying. I’m not even sure how I ran across these, but I’m so glad I did. I placed them on top of the box spring and under the mattress, and it made an instant difference. No more sagging. I didn’t even realize how bad the sinking was in other parts of the bed until I put these in — the foot of the bed was just the most obvious.Since adding these, my mattress feels way more supportive and my back doesn’t hurt like it used to. It’s literally just wood slats, but they saved my back and fixed my bed without having to replace anything else. Highly recommend!

Was skeptical of Zinus, they have "2,000 lb." bed frames for memory foam mattresses that break in a year (white label: it's the same as many other frames for $125.)But these did the job. Vertical wood slats combined with my existing bed frame's metal horizontal beams means no sagging, every part of the bed feels even, and no dipping.Some notes:-- For spring mattresses, this will NOT replace your box spring. Seen a lot of pics of folks putting this in traditional metal bed frames expecting it to work. (Same as any other long planks of wood: if a kid jumps on the mattress, without cross members, it'll snap. What is expected here?) This is meant to add stability to beds with existing horizontal slats of some kind (wood, metal, etc.) that are just too far apart for a mattress to be well supported.-- Sliding around is real, but again, this shouldn't be the sole thing holding the mattress up. This is intended to be part of mattress support, not a sole support. After placing the mattress on, I let the planks shift inward, then pulled them back to the edge and checked underneath that none were overlapping or doubled up. All set.-- My current bed frame has horizontal slats, but the measurements were over 6" apart, which is against most memory foam mattress warranties. By putting these over it, it has a "lattice" appearance combined with the horizontal slats, and the wood makes contact with each horizontal slats distributing weight across all of the slats evenly (versus each horizontal slats receiving pressure and shifting/bending/buckling over time on their own.)-- Mold sucks. I'm sorry for those who found them with mold shipped. This is common with wood products and shipping containers + moisture + time, it is extremely possible these left the factory 100% but had spores on the wood or they transferred on from other contaminated product mid shipment. Its also possible Zinus failed a quality check. I'm not writing this for them. I bought these, no freebies or review samples here.I'm a big guy, but not tremendously so. 280 lbs, 6 ft. tall. And I've learned that most weight ratings on mass-produced bed platforms are nonsense. Anything spot-welded breaks over time just as easily as wood snaps given time and repeated pressure. I don't even slump down when I'm tired, I'm careful to sit each time before lying, and it still happens. The goal is getting more time out of a cheap bed frame, versus paying $600-1,200 for something with all sorts of feature I don't need (shelves, upholstered pillow-stitch headboard, trundle bed, drawers, etc.) that is likely assembled the exact same way with the same quality of parts.In closing, you can't pay for quality without overseeing someone custom-building it or doing it yourself. So, stack the deck where you can. This isn't going to replace a box spring. But it's a lot less unwieldy and likely cheaper (wood prices haven't really come back down) than getting a plywood sheet from the hardware store cut to fit your bedframe, stapling a fabric cover over it, and laying over the slats to 'back them up'. That's what this is for.

Exactly what I wanted. I had a bed frame with existing horizontal slats, but they were farther apart than what was recommended by the mattress I have. So wanted something to add to it and these vertical slats worked like I intended, simply laying them on top of my existing slats and frame. They were only about a half inch thick and still fit inside my frame. Picture shows the underside of my bed frame, with new vertical fabric wrapped slats above existing metal slats

Good product, seen a lot of complaints that it slides a bit but easily fixable with double sided tape in a couple spots. Worth the money

Our twin only came with 3 slats and it was a disaster. We added this and immediately the issue is resolved! Amazing

Got here faster than expected, and is a perfect fit. Anyone needing additional support for their mattress should look into this.

A product that is sturdy & well made. It is a simple solution for a simple problem. Reasonable price. I don't see how anyone can be disapointed.

Works okay, but most foam mattress manufacturers suggest no more than 2.75" between slats. Check your mattress warranty thoroughly before purchase or you may not be covered if you have a problem. Also comes in two separate pieces. Lots of people have complained about them sliding around when trying to put the mattress back on. This can be easily remedied by screwing down the outermost slats to the cross members you should have below. You don't have to screw down all the slats as they're held in place with the material that holds the slats themselves. You just have to screw the outermost slats on each of the two sections, for a total of eight 1.25" drywall screws for the whole project on a full size kit.
