Review on 4 Inch Bed Risers, Set of 4 Pack – Lifts Height by 3.35 inches, Heavy Duty Furniture Risers for Under Bed Storage, Black by Eloy Boelkens

These risers quickly gave me 2 inches of lift on a bunk bed that was too low. However, I didn't trust the double stick tape that came with it, so I used screws to attach them to the underside of the bed frame. I also didn't like the plastic stoppers at the ends of the risers. They were too soft and stuck to the carpet when I tried to move the bed. I couldn't move the bed an inch without them coming loose. I had to put the bed in place and then lift each leg to fit the cover underneath, which was a little tricky as the bed was pushed against the wall and pushed into the corner. Before moving the bed again I need to attach some hard plastic to make it slide on the carpet. I really didn't like the plastic stoppers and would have returned these risers if I had had more time before needing them. However, they do the job I needed them for and the grandkids have already used the bed so I think that's a plus.
