🪑 Shepherd Hardware 9083 1.875-Inch Spiked Furniture Cup, Transparent Plastic, Pack of 4 Review

Not suitable for medium plush rugs. The chair legs slip off the protectors, the protectors tip onto the carpet. Probably suitable for thinner carpets or carpets. Otherwise not recommended.

They're durable, but the narrow hem around them won't hold up a crib with thin metal legs. Perhaps a heavier and thicker leg would work better on a piece of furniture.

I put them under the bed to protect the carpet. The cups are clearly concave inwards. Under pressure, the lower peaks rounded and started pointing in different directions. The plastic inside the inner curve shows these very thin stress cracks.

Robust. They have much higher spikes than other products. Good for heavy objects or high carpets. We liked the little spikes for our rug. Wouldn't recommend using them with tape, we had to rip them off our furniture. The tape or glue was very strong.

If you have carpet under your bed or sofa, they work great. I have installed them under all my heavy furniture and after you remove them you just vacuum the stain and the marks are gone. Very useful and prevents damage to your carpet. I will buy again.

I have used this product for its intended purpose. The key is to buy the right size and in my case this size was perfect for the legs of the furniture. I've used similar products for years to protect carpets from being crushed by heavy furniture that's been in the same place for years. I recommend using this product and will buy again, in fact I bought more round ones to fit under the round furniture legs.
