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 – 2.38-Inch Standard Width

Our mattress was sliding on the frame and needed more support. This has done the trick. It comes altogether (no assembly needed) and we just had to roll it out. We placed it on the frame (perfect fit) and set the boxspring and mattress on top. It is sturdy and has given the support our mattress and boxspring needed. We've had it for a few weeks and have no complaints.

We wanted to get rid of our box springs that were squeaking. This was perfect. Quality is top notch. Very strong and sturdy. Our mattress actually works so much better with this than the box springs. Instructions and not the best. We put it together inside the frame which seemed to be easier. We have a 4 poster wood bed with a headboard and footboard that has curved corners. So we were concerned that the frame would not be able to fit inside. It fit perfectly and makes the bed feel sturdier.` So glad we made the switch out of a box spring

I didn't want my mattress laying on bare, unfinished wood slats, but still wanted air flow. This was the perfect answer. The slats themselves are sturdy, and the cloth covering allows air flow. Good price, too. Fit my queen bed perfectly.

Bought this for added support for a hybrid mattress. Definitely made the mattress feel more supported. Was easy enough to put on the bed frame and the fit is perfect. Gave it 4 stars because it was covered in what I would call trash, like it was laid on the floor and packaged up. 🤔. Haven’t slept on it yet, but just laying on the bed you can feel the difference.

It is ok, but they don't stay in place. It contributes to the mattress moving around

Fit perfect. Great base support for my memory foam mattress. I never expected that getting a memory foam and not having a box spring underneath would compromise it's stability. I wanted a steel frame because it's high and the storage is better underneath but the way they come now there's no support without a box spring. This fixed the issue without making my bed a lot higher and harder to get on.

These work perfectly for my king sized bed. I originally bought a metal box spring that squeaked often and loud enough to wake my up in the middle of the night. Thankfully these slats are solid enough that I have not had any issue with noise or shifting. The height and width fits perfectly in my king frame. I will say the velcro to keep the two sets of slats together is a joke though. Any slight tug and they separate from each other. I think the fabric around the slats is a gimmick. The only reason I bought these ones is because they were cheaper than slats without the cover on them. Thankfully there wasn't anything to assemble, just remove from box and plastic wrap and layout on the bed frame.

We spent thousands of dollars on a mattress and had no clue the box springs were made wrong until we tried this. What it was like night and day for my back and now my husband and I can sleep together and we don’t roll towards each other.
