Question: How many risers come in this order?
Document: I had to remove the other three in order to sleep in the bed that night. With no cord holding onto the risers, I could not get one to come off no matter what I did. Finally, I got a sturdy bungee cord, put it behind one riser and held the cord firmly as I pushed the bed. In nothing flat I had removed all 3 risers.
I had lots of concerns about this product when I first purchased it. There were many reviews that made me nervous about these risers breaking in the middle of the night. My wife and I have been using them now for about 2 months, without any problems at all! I bought two packs of the stands, per the manufacture recommendation for a King bed, and used just 6 of the 8 we received.
I ordered these risers in order to raise my husbands chair. His legs are giving out and finds it hard to stand up from a chair too close to the floor.
Granted, this is my first time using bed risers, they were a little tricky. Once in place they don't move, although I am worried that a good enough movement, they could buckle over, because thats exactly what happened when we were trying to set them up. I was moving in so my bed wasn't all the way in place yet, when we went to move it over just a little it would come right off of the risers.
My Mother weigh 360bls +, and the bed risers is very very strong, also you can storge things under the bed as well. Yesssss, I would I would tell all my friends about these bed risers, these bed risers is very strong. I will order to more set of them.
I've used risers before many times and these felt a little less solid than ones I had used in the past. Still I gave them a try and POP! right through the top, as complained about by other reviewers.I would STRONGLY recommend buying risers in person. If I had seen these in the store I probably would have known better because they're so much lighter than ones I had used in the past.
I bought these bed risers because my husband had hip replacement surgery, and doc said his knees should not be higher than his hips when he sits down. Since he's a tall guy, everything he sits on has had to be lifted. We've raised his recliner and the sofa as well. I recommend this product to anyone who needs to sit higher in order to stand up, especially after surgery.
I recently moved into a small bedroom in an apartment share and had to really consolidate in order to keep everything...Back in college, I had the standard 5-inch bed risers and I remember having to leap into my bed because I'm only 5'2. They were great for space for definitely made my bed too high. These 3 inch ones don't feel that way. I have a queen-size bed.
Great buy if you want lots of space under your bed and something that will not come off by accident unless you do something really dumb as I did.
Not too much to say about these other than they do what they're supposed to. They look fine and aren't as tall as many others, which was better for my needs. Inexpensive too.
Answer: yes
