DMI Foldable Box Spring, Bunkie Board and Bed Support Slats, No Assembly Needed, Full Size Bed Base, 60" x 48"

The short review is: I've been using this since the latter half of 2022, and am never going back to using mattresses again. I used to use a mattress like most people. Unlike most people, ever since my 30s I'd sometimes, and later quite often, wake up in the middle of the night and mornings with a "paralysed" feeling in my neck, lying on my back. I'd have to use my hands to rotate my head sideways and then would turn the rest of me sideways, so that the feeling would subside and I could use my head again. On some days, I'd wake up with a terrible pain in neck and/or shoulders and felt something somewhere had got stuck into a "wrong" position. I'd be unable to move my head using my neck, and would have to turn using my whole body instead, to see in other directions. An added hassle driving to work when checking for cars, and pain in my shoulder merely turning the wheel. This feeling that some muscle or something got into a knot or stuck in the wrong position somewhere inside would last for the whole day if I was lucky or for weeks if I was not, easily made far worse when I made movements which I hoped would get it "unstuck". Sometimes spending half an hour lying on the hard floor on my back, with my legs pulled out and arms stretched out or against me would manage to get things unstuck at last (some pain would linger) but it didn't always work. Things would eventually return to normal when I shifted from my bed with its mattress in my bedroom, to sleeping on the floor for days on end until the pain went away. In the back of my mind, I'd think I just needed to sleep on the floor and not on a mattress, but in half awake state I'm always paranoid about any creepy crawlies that could perhaps drop by to visit me on the ground if I were to sleep, so I'd go back to my bed eventually. The cycle of horrible pain would repeat. I got a new sturdy mattress, hoping it would mimic the floor. The pain from getting into a stuck position was initially less or less often, but it would always strike again. Then I just consciously envisioned what I wanted: my metal bed has inbuilt metal latches. It should be able to support some hard metal plate or board of some kind. Then I could treat it like the floor, and I'd be happy. If I could just find something like that. It wasn't easy to locate anything. Where I was born, my grandmother had a light, fully metal bed that she'd put her thin mattress on. But my searches for something similar never turned up. Also, it felt wasteful of my existing metal bed which was almost there. I thought to search for things like bed boards, which eventually led me here. This is simply made but very to the purpose and works. While my cushion is still not quite right, so that if I roll onto my back and sleep in that position for too long, my neck can hurt until I turn back to my side, when things go back to normal, I don't wake up with lasting pain any more. This was the cheap and easy answer for me. I want to thank the makers for making just what I needed. Now I need to find a cushion right for me that doesn't require me to mould it to fit me first (I seem to never get that right), so I can sleep on my back too. Although, per a StonyBrook study, sleeping on the back, thereby sleeping on the back of the head, is associated with Alzheimers (see "Could Body Posture During Sleep Affect How Your Brain Clears Waste?" article 2015 and "Head Position During Sleep: Potential Implications for Patients with Neurodegenerative Disease", Levendowski et al 2019), so perhaps I should take my neck hurting when I sleep too long on my back as a regular reminder to switch back to my side. (It's also bad to sleep on your stomach.) Sleeping on your side clears out brain waste and prevents neurological diseases. This was an aside, the point is that this lovely bed board has made my life normal again by making my sleep restful and something to look forward to, instead of a potential and regular cause of days of pain. If my experience sounds familiar to you and nothing you've tried works, I found that this foldable, simple but hard base in place of a mattress solved my problems. You will need to layer as it is harder than the carpeted ground. I can't thank DMI enough for making what I needed, and so affordable to. Yes it's basic, but that's all that was needed.

Save your money - this thing is super thin and flimsy- definitely not worth the money. Bought a pair for twin mattresses that we bought. We have older antique wood and metal frame beds with four 1 x 4 slats per bed and we had a hard time laying the bunkie boards in without them falling in between the slats Also, not able to properly make up the beds because the dimensions are so small Not worth the cost

Folding pieces of wood (think of the backing of Ikea bookcases and other furniture like another reviewer said) held together with stapled cloth that fits a fold out double bed with just a little room around the edges. Not too much room so that you'd notice laying down but enough so that you don't have to cram it in. Surprisingly this actually works in supporting a saggy mattress or in not feeling the cross bars of a fold out bed. I was worried that it wouldn't be enough support, but i was pleased to find out that i no longer felt the cross bars through the mattress. I sleep on a fold out bed every night and with this insert I no longer wake up with a stiff back from an uneven night's sleep. I have a foam mattress that I use and I used to feel everything that was underneath it, but now I sleep on a flat, stable surface. It has made a world of difference. And since it easily folds up, I can store it under the sofa when I fold the bed up during the day. I highly recommend this if you sleep on a fold out like me, or if you have a saggy mattress or a bed that needs support.

Works great! Used it with a queen sleep number mattress over a slatted base that wasn’t quite giving enough support, even when cranked up to a sleep number of 100. Took a star off because there’s about a foot and a half on each edge, so not a perfect fit and there’s really no way to combine boards to make a 60”x80” queen size.

This thing is a pain in the neck. I’m single and I had the hardest time getting this under my Casper mattress by myself. It’s made of some cheap splinter board and it’s not very durable, although now that it’s under the mattress it hasn’t broke or anything. It has provided extra support, so that is a positive. I was worried about how far apart the slats were on my bed frame, that’s why I purchased it. Technically it’s doing its job. It does however move and shift on the slats of the bed frame. Once it moves or shifts out of position, I find it incredibly hard to get it back to the position I want it to be in. I only have a full size bed and one of these only goes under a portion of it. If I had to choose again I would look for something else. This might be ideal for someone else though, especially if there’s more weight on the bed so it doesn’t shift.

Fit just right thanks my slacks velco came a loose

I am shocked there aren’t more products like this on the market. So simple yet effective. I bought an expensive, very thick memory foam type mattress 2 years ago. The 1st year was good, but the second year now I am waking up daily with an aching lower back that continues into the day. I noticed that my mattress was somewhat sinking into the gaps between the slats in my mental frame but thought that can’t be causing pain like this! I was prepared to buy wooden slats that are closer together, more expensive option, or a whole new mattress. I was skeptical that these inexpensive boards would make a difference in my very thick mattress, but I was wrong! I noticed a difference in firmness immediately. And after just 1 night, my lower back is in less pain. Hoping to resolve the pain all together! Thank you! For those saying that it slides around too much- I bought one of those rug grips for $10 that you put underneath a throw rug, and placed that between my metal frame and the board. Worked like a charm.

It’s cheap but will last a year or so. Pretty fragile for what it needs to be. One wrong move and it breaks.

Worked like a charm

SO disappointed with this purchase so it was immediately returned. It was light, flimsy and totally unsuitable for the job required - besides being very expensive. I wouldn't give it any star rating if I could. A piece of thick ply board the size of the mattress has done a perfect job at less than half the price!!!

للأسف لم يفي بالغرض ابدا

Just go and buy a bit of board! What a ridiculous price!
