ZINUS Compack Fabric Covered Wood Slats, Bunkie Board, Box Spring Replacement, Natural, King

I currently have a king size bed (two twin mattresses pushed together), and a few sets of the provided slats on the side that I primarily use keep popping/falling out, and they are next to impossible to put back in. This inevitably led to a sagging mattress which in turn led to back pain. I figured there HAD to be some kind of a way to fix this, so upon doing some research for bunkie boards, I found these under the highest rated ones.Let me tell you, I don’t think I could be happier! They fit PERFECTLY (I did have to use a tape measure before ordering them), they are very lightweight, and they fold and unfold very easily. I am amazed at how durable and supportive they are, and the fact that there is a set of two for the king size works great for my bed. They were not badly priced either, and they were here next day (I badly needed them)! If you have a sagging mattress and need extra support, buy these - you will NOT be disappointed!

Item shipped fast. Was packaged good. My bed was sitting high so I got this to replace my box spring. Worked perfectly. Very easy to install. Just took it out of the box and layed it onto the frame. Fit perfect (Queen size). Good quality. Bed is comfortable. Would definitely recommend.

Bed is more firm, squeaks less, & probably more steady. no sliding yet. Perfect size for my queen. Given the other reviews this product exceeded my expectation. Sliding has not been an issue as of yet, only got it yesterday. Size is a perfect fit for my queen. Super easy to use and I feel my bed is more sturdy as the weight is now distributed across all the support beams. Excellent choice especially if you have a memory mattress foam and are concerned about the gaps in the slats on your regular bed frame. Also the delivery woman was exceptional.

It’s sturdy and works just as described.

I have an Ikea Brimnes bed with Luroy slats and a very heavy hybrid mattress (Stearn and Fosters Kirkland mattress from Costco). As a stomach sleeper, I am very sensitive to any dips in a mattress, so I have been sleeping close to the center beam where the mattress has the most support. Thanks to other reviews for this product, I decided these vertical slats laid over my horizontal slats might extend that center support to the whole bed. I put carpet tape on the last row of horizontal slats at the foot and head of the bed to prevent shifting when I rotate the bed. I used cheap Duck brand carpet tape which allowed me to easily reposition the slats before laying the mattress on it. Despite sliding the heavy mattress over the slats, they didn't shift at all. The wood is good quality, and I really like that it is encased in material giving the mattress even more support, similar to a foundation. The crisscrossed pattern seems extra supportive while still allowing the mattress to breathe. Just one more slat in each bundle would have been perfect, but combined with the other slats below it, this should work. Hopefully,I didn't already damage the mattress beyond redemption with those cheap Ikea slats. I will update my review in a few weeks or so after trying them out for a while. Until then, I'll keep my fingers crossed that these Zinus slats finally helps my back pain!
