Antrader 4Pcs M10 Thread Adjusta... vs 48 Pcs Brown Premium Chair Leg S...

Bought them to support 400lb cnc. Used on a sleep number adjustable base. We move the controller around every once in a while, and it's extremely heavy.

Very well made. Stretches to any size and holds its shape. Great for hardwood floors. Used to cover bottoms of all our dining room chairs.
