adjustable (heighth and length)metal slats/mattress support rods to fit any size bed (twin to king) and depth to floor up to 12"/replaces wood slats so you never have to buy wooden slats again or put up with them bowing or splitting making support a problem.
I bought these a couple years ago to use with a queen bed we were having trouble with the wooden slats not holding me, her, box springs, and mattress. This was the solution. They will support any weight you have and fit any bed width and depth.
Now we are not using them as she switched bed styles. I paid $80 each, $270 total to get them delivered.
Your solution for only $40 each. They work great. There are 3 of them.
Buy all 3 for $100
