They protect hardwood, laminate, tile and carpeted floors, reducing wear and allowing furniture to slide more smoothly.
Felt pads and silicone components absorb sound and lower friction, vibration and noise so furniture slides more quietly and more smoothly.
Nail-on glides use a stainless-steel nail together with a durable felt pad and often a high-duty nylon backing to hold the protector securely in place and extend lifespan compared with stick-on pads.
Metal replacement legs include non-slip, wear-resistant rubber pads on the bottom to help prevent floor damage and come with pre-drilled holes for secure attachment.
Common materials listed are nylon, plastic, silicone and felt; some products use iron (metal) components and include rubber pads on the bottom.
Attachment methods vary: some use a stainless-steel nail (installed after pre-drilling—avoid direct hammering), others are slide-on caps that fit without tools, and metal replacement legs commonly have pre-drilled holes and are offered with screws.
For nail-in protectors: pre-drill and avoid direct hammering; pointed nails are a child hazard. For slide-on or stretch-fit caps: no tools are required—choose the correct size for a secure fit and avoid over-stretching to prevent deformation.
