Great product! I like this company a lot- easy to assemble and sturdy.Fit my mid- century bed perfectly

This fit the two antique bed frames (double/full size beds) we purchased them for, really well from head to foot. The width is slightly less than the ledge the bed slats sit on, so we kept the bed slats, and placed the bunkie board on the slats. It works as a box spring replacement perfectly well. The beds we have are antiques, and the slats kept getting spit out, usually around midnight, and dumping the poor sleeper onto the floor with a loud BANG! Discovering that the slats had shrunk in our dry climate (Colorado) and the head board 'leg' was loose causing a slow, creeping, bow legged effect which drifted the side rail outward as the weight on the mattress pushed down/outward and the slats suddenly lost purchase. We remedied this by screwing the slats to the frame-ledge before adding the bunkie board. The bunkie boards are sturdy, don't rattle and now that we've screwed the loose parts down, everyone sleeps through the night without 'sudden relocation'. Assembly is easy. The second box arrived looking like it'd been through a shredder, and it wasn't until assembling the parts that I found some mangled corners. but I was able to bend the two mangled corners back into place with a pair of simple pliers (I'm a 60 yr old woman, so we're not talking about a beefy welding wizard here). My hubby was supposed to help, but he was on a business trip with the second one arrived, so I huffed and puffed the assembly solo. The instructions are blessedly simple and it doesn't take long at all. And the huffing and puffing was due to manhandling the mattress onto the bed by myself. The bunkie board I simply assembled on top of the bed slats - no lifting required, and the room was too small to do it anywhere else. Just watch your feet going between the slats carefully so you don't embarrass yourself (not that anyone would trip over a bed slat, like, umm, I might have ...)

I have one of those fabric bed frames with fabric headboard. Its really beautiful. However the boarder frame on the inside that goes around the inside of the bed where u put the slats down is wood. I've had 2 of these bed frame beds and both had wood slats. One came with a ton of slats and the other came with only 4. The wood slats broke on the first bed, they arent very good for these beds in my opinion. Not strong and sturdy wood slats at all. But my point is this product is a perfect solution. I ended up throwing out the frame on the bed that broke because where the breaks were it couldnt be salvaged. I didnt want that to happen with bed number 2. I put the frame together and the 4 weak slats. Then this product came to mind. My first bed was a regular mattress and I guess the wood slats replace box spring so I didnt have box spring. The mattress was older and everyone in my house had a memory foam mattress so I finally upgraded. I have a queen frame and queen mattress. Not only was I worried these weak wood slats wood break again but my mattress was sinking between the slats. Everything felt like a horrible nightmare bedtime wise. This product saved me. It was completely simple and quick to put together. You simply attach each side together to form the rectangle board frame. All hardware and tools are included. Only took a few minutes to do. Then you just snap all the slats in. The just push down into all the little openings, you dont even have to mess with twisting and turning more screws. I hate putting furniture together but this was a simple fast easy breeze. I laid this board right over the wood slats and it damn near was a perfect fit. The length is perfect fit for a queen bed. I gave 4 stars and would have gave 5 stars but I found one issue. Now this holds my mattress up where its supposed to be, no more sinking and unevenness. The bed supports it well, everything is strong and sturdy. 4 stars instead of 5 is due to the width. Its a little short but not by much at all. I couldnt find anything with a tad bit bigger width that I needed and all descriptions with these measurements said its for the average standard size queen so I just took my chances. Its still enough for me to love it and keep it but if I had to guess I'd say it could be about a centimeter to a half inch longer in width and it would have fit right in snuggly. This is why I had to lay it over the wood slates or one side wouldnt sit up properly on the wood boarder on the inside frame. It was either the description or other reviews that said laying it over the current frame/slats was fine and it is. Hope this info helps. I'd buy again if another bed in the house has issues with the wood slats again

We are very impressed with the quality of this product! Didn't take pics but probably should have..figured there are plenty in these reviews. Not counting breaking down the bed, removing the old box spring and cleaning under bed, putting this together took all of 15 minutes. Not only did it fit perfectly, all the pieces were clearly marked, and instructions were easy and clear. It was actually fun to put together ❤️ After having read reviews with tips, we did lay 3 sheets of pegboard on top of it, as well as non slip rug cloth on top of that to insure mattress would not move. Heavy duty construction...extremely well made...kept telling my husband how impressed I was., and what a difference in comfort and sleep! No sound at all, nor movement. Just be careful upon waking and getting up...the floor is much closer now! Lol. We would emphatically recommend this product if you're in need of good quality support for your mattress.
