TRIPLE TREEBed Slats Twin Size 39.8”Lx2.1”Wx0.7”H, Heavy Duty Wooden Slats Mattress Support Pack of 13 Count, Replacement Spare Parts Mattress Support, Fits Most Beds, Twin 39.8 Inch

These slats fit perfectly on my kids twin size bed. I had bought 2 previous ones, different ones. And they didn’t fit the bed. But these ones fit perfectly. They are very sturdy, they don’t look like they will break so easily so that’s a big plus. And it was very easy to assemble and fast shipping. If you are looking for some. These are the ones you need.

Best slats my boys were wrestling on the bed and one jumped on top of the other and I just heard a big cracking noice and sure enough the slats had broken I purchased these and oh boy are the sturdy boys have been jumping like crazy and nothing. Definitely recommend
