CreativeWare Plastic, Adjustable Bed Riser System in Black, 8 Count

i love these because it makes my bed so high when i get up in the morning i don't have to struggle i just slide off lol and it helps create so much space under the bed compared to the original size ones i had before just a tip if u have bed bigger than a twin i suggest buying two packs because for example my bed has two extra supports under The bed in the middle and so does my mothers bed....i have full size and my mother has a queen

You get 8 pieces. Four risers are 3 inches high and the other four risers are 5 inches high. I used the smaller set on my office desk and the larger set on my bed. OR you can use them together and you would have four risers 8 inches high. They are very sturdy and they lock together snuggly. The area on top of the 3 inch riser where the leg rests is 3 inches square and it has a solid 1/2 inch lip so that the leg does not slip off. Only drawback is that the black color does not match anything of mine. I may spray paint them the same color as my carpet. I will be ordering another set.
