Greaton, Wooden Twin Bed Slats for Support Under Mattress with Cover – Replacement Wood Slats for Twin Size Bed Frame – Under Mattress Support Without Extra Height – 3.38-Inch Standard Width

Wonderful solution for our bunk beds with very few supports underneath mattress so that we could remove box spring for more vertical space. Have held up great for over a year! Highly recommend.

This is exactly what we needed for our son's bed. We had wood boards across the frame under the mattress, but they never stayed in place, especially with kids jumping all over it. This set supports everything perfectly and even fixed the sagging at the end of the bed. I honestly do not know why we waited so long to buy this. The covered wood slats keep everything from shifting and give the mattress a smooth, even base. They do not add any height, which is great for tall mattresses or platform beds. The airflow is noticeably better too, since the gaps allow heat and moisture to escape. We still put the other boards we were using across the top of this to add extra strength, because, well, kids. It all works together really well and feels solid. Installation could not be easier. They come bundled, no tools needed, and lay right on the frame. The quality is excellent, just make sure to measure your frame before ordering. Highly recommend if you need a simple, sturdy upgrade for your bed.

Wanted to give this 5 stars but...although it seemed like it would work well with the bed we had, being folded vertically, when unrolled and placed under the mattress, it slides on the side my son tends to sleep. It was a decent value and fit well. It is sturdy and I think it would be great if it didn't slide. Perhaps I should have laid it out longer. All in all, it is a great product, I love that it is wrapped, so the boards are not bare. It came well packaged and easy to set up.

Exactly what it says it is, great quality, a little shifty on my bed frame however, I need to get one of those non slip things to put under it. Perfect size, works well.

My expensive latex mattress began to sag in the middle after a year. Adding these slats crosswise over the existing frame slats changed everything for the better! Easy peasy assembly

Product in gerenal seems quality, but beware if you're purchasing this product to meet a specific mattress warranty requirement. Product details stated that the heavy duty has 4.5in between slats. We're measuring 5" minimum and because the slats can slide some within the fabric pockets, it can be up to 5.5". now we have to take the trouble to repackage and return, when that could've been avoided with accurate product information. Also not sure why the slats are manufactured to be 78" (across all queen vertical options with this brand) when standard queen mattresses are 80"? We had already had to compromise there since the alternative products that were 80" didn't meet our slat spacing requirement. The horizontal slats from this same brand we purchased for a different bed were accurate slat spacing to their product informaiton.

If your mattress feels saggy or you wake up with a stiff back, try this before investing in a $X,000 mattress! This completely changed my bed, which didn't have enough slats to be a "true" platform bed, and fully supports my king-sized mattress. It fits perfectly from end-to-end and side-to-side. It was super easy to install, two of them velcro together in the center, and they disappear entirely even though my side rails don't have a lot of vertical space.
