Greaton, Wooden Full Bed Slats for Support Under Mattress with Cover – Replacement Wood Slats for Full Size Bed Frame – Under Mattress Support Without Extra Height – 2.38-Inch Standard Width

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.

Definitely a must if you have a memory foam type mattress. Only thing I would suggest is adding some type of grip to hold it in place if your mattress slides on its frame at all, this will make it slide more. Still worth it and gave our mattress & frame the extra support boost it needed.

Good board, but I do feel it is struggling holding the weight. I have an 18” king sized bed that is quite heavy and every time my husband gets in bed you can hear it creaking. Also getting the bed on top of the boards was a challenge. Since there’s no non slip grips, the boards slid as we put our mattress on. If you can easily lift your mattress no problem, but for us two, definitely wasn’t going to happen.

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

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

I had purchased a used bed frame that did not have slats. These fit well and gave extra support.

I originally ordered wooden slats but they kept getting delayed so I cancelled my order. I found this item and it looked to be better than slats. And they are! It fits perfectly. It comes in two pieces and velcros together. They don’t move at all and are sturdy. I was worried it was going to be a piece Of cheap board but it’s not! The mattress now doesn’t sink in between any gaps. Worth the buy!

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.
