Wobble Wedges Rigid Plastic Shims, 30 Pack - Multi-Purpose Shim Wedges for Home Improvement, Work - Plastic Wedge, Table Shims, Toilet Shims, & Furniture Levelers - Black Leveler Wedges, Leveling Feet

I bought these to stabilise a washing machine, which sits on an uneven floor. Three of them stacked has worked perfectly - the washing machine no longer dances noisily across the floor. I'm very happy indeed. They're tiny and unobtrusive (which really isn't important re the washing machine, but might be if they're being used for, say, a dining room chair or a side table).

Good

Can be used individually or stacked together as they won't slip. I've used them on cupboards and dining table and they work well

These are perfect for that wobbly table. So much better than those bits of folded card!
