Review on 🖼️ 1-Inch Prime Line Products 9005 Frame by Mark Lodge

I measured as shown on the product image (one inch on each side). They don't fit in my frame even though the frame is 1" wide on each side. The boxed liner has the size section conveniently deleted, as is the inside of the liner showing 1 1/4 measurements for each side. How can they get confused?! So I think my mattress is set and I'm staying on the floor until I find the right brackets.
