Bed Risers (Set of 4) Lifts Height 1",2",3" or 4",Natural Wood Furniture Heavy Duty Leg Risers Lifts for Sofas Table Desk Chair Couches with Non-Slip Rubber Pad & Non-Slip Recessed Hole (4 Pack Grey)

These were nice risers. Could be used to furniture but also in a food display etc. nice and sturdy, .

The spacers are nice I wish they included 4 more grip pads to have one on the bottom and one on the top

I'm using these to raise the height of an Ikea desk to allow an Aeron chair to be pushed all the way in.Two things I ran into:1) A stack of two under each leg was just shy of the change needed to provide rub-free clearance to the chair2) Positioning the desk with the risers In place tended to cause one or more legs to lose support as the riser(s) tipped over. Even on a very smooth hardwood floor there was too much friction.So I added some Magic Sliders to the bottom of each set and, being a bit careful, I can now move the desk around as needed.Bonus: the height is now perfect - no more rubbing.
