So a lot of reviews mention breakage. Certainly I would expect bed risers to hold a LOT of weight, so that's kinda sad.
However, I use these for all kinds of things! Think your desk needs to be a few inches taller? My end-of-the-bed TV stand isn't quite high enough and these work perfectly!
Yep, they may fail for beds, but I love these for all my other furniture that needs a little boost. And you can't really beat the cost, in my opinion.
I had these for about 5 months on a seldom used guest bed, and while they did provide a good lift for under-bed storage, one of the feet of the bed just broke right through the lifter. I'd recommend avoiding this product.
I LOVE these things. I bought them when I was in college, living in a studio apartment and I kept those plastic drawer things under my bed to store all my non-hanging clothes. So they are almost 5 years old and I still use them now in my small apartment to keep all kinds of things under the bed. They are so tall that I can fit 2-3 stacked laundry baskets under the bed, plus other random [stuff]. I definitely recommend.
I bought these risers because my new bed skirt was hanging on the ground. Not only do they allow for storage underneath the bed, but the make the headboard and bed become the focal point of the room. I was very surprised that they make the bed feel secure....not wobbly at all. If you use them with a bed skirt like I am, you can't even see how much stuff is under the bed. Clever product.
