    • Great Bunkie Board for Hybrid Mattresses
Size: Queen (59.3x79.3'')
If you have a standard-size bed frame, this is the perfect choice for a new hybrid mattress. I had purchased the manufacturer's foundation with a new mattress, and it did not fit. They suggested I buy a bunkie board, which they did not sell. I mistakenly purchased one without carefully reading that the bed frame slats would need less space between them to use it. I purchased this one, and it was a perfect fit. I hired a service to assemble it, and it took less than 10 minutes. Meliusly provides meticulous instructions for easy-to-understand assembly. All parts are labeled and correspond to the illustrations. The guys installing it were impressed with the tools included, too. This bunkie board fits the mattress, adds just enough height and is exactly what I needed. If you have a bed frame with a headboard and footboard that you don't want to replace, this is an excellent bunkie board! And it's a great price for a bunkie board, too! ... show more

    • worth every penny!
Size: King (75.3x79.3'')
Absolutely transformed my sleep — worth every penny! I didn’t realize how much of a difference a quality bunkie board could make until I got this one. From the moment I set it up, my bed felt sturdier, more supportive, and incredibly comfortable. It completely eliminated that slight sag I didn’t even notice before, and now my mattress feels like it’s brand new again. What really impressed me is how solid and well-built it is while still being easy to handle and install. No noise, no shifting—just reliable support every single night. My sleep quality has genuinely improved, and I wake up feeling more rested and refreshed. If you’re on the fence, don’t hesitate. This is one of those simple upgrades that makes a huge impact. Highly recommend to anyone looking to improve their bed setup and overall sleep experie ... show more

    • Perfect - but recommend you measure and use shimms if needed...
Size: Queen (59.3x79.3'')
I have lower back issues and I saw an immediate improvement. Woke up with less pain. Assembly was relatively easy with clear instructions and notations on the frame itself. I did decide to add shims to the frame to insure there were no surprises (I highly recommend you premeasure the inside of your bed frame to know if there will be any gaps. Probably unnecessary, but I have peace of mind knowing the bed board will not fall through the frame. These are what I ordered and used and they worked perfectly. https://www.amazon.com/dp/B0G4QJW1D6?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 ... show more

Works great with the Ikea Songesand Full Size bed frame! Super easy assembly, and the seller was kind enough to include a handwritten note and complimentary eye mask. Really excellent product.

Review Image by Christina Diaz
Overall a great product. Easy to assemble by myself however one of the inside rails was slightly crooked at the base which made it extremely difficult to align the screws with the holes. Finally- was able to get the screws in tightly. That's my only disappointment. Why wasn't their quality control before sending? The crooked piece was obvious. But I still do love the product and would recommend. ... show more

    • Very solid support
Size: King (75.3x79.3'')
Extremely solid and a difference maker for our king mattress that was feeling somewhat flimsy. Tried some of the other cheaper bunkie boards and they just are not as solid as this one and don’t provide as much support. The amount of metal beams really makes a difference. Also tried 3/4 plywood before this which also provided some support, but not like this. Easy to put together and a high quality product. ... show more

    • Great replacement for box spring!
Size: Full (53.3x74.3'')
Just what I needed! We have an old bedframe for my son's bed but no box springs. The bed was sagging terribly! This turned his bed frame into a platform bed. His bed is just the right height for him to get in and out of so I didn't want a box spring to add extra height. This product is just what we needed. The bed is nice and sturdy now and I can hold out on buying a new mattress. ... show more
