I'll start by saying I did not buy these for a Ziyoo bedframe- I have an Amazon Basics that has recessed slats but not deep enough to prevent slipping.

These gaskets feel strong and well made, and I'm sure they fit their intended Ziyoo bedframes well. For mine, a slight bend on each arm ensured a tight fit to the bedframe.

Almost no one makes metal brackets to prevent mattress slippage, but these do the trick! I've bought another set for our guestroom bed, and my sister-in-law is getting some for her similar-style metal bedframe from another maker. Whenever we get a King size bed to replace our Queen, another set of these will by ordered- plus that may bedframe be a Ziyoo considering how happy I am with these.

This product works for the intended purpose keeps my mattress from moving. However I wish it would have came with some screws to hold it in place. But I use some screws from home Depot and put some nuts on the back. Even though only three star review I would still buy again it was very affordable and worked for the intended purpose.
