They look like Geo-Mattress. I haven't opened them yet to put on the beds, but the look right on the ends.
The outside plastic was a little dirty but insides look okay.
I have used Geo-Matt for the last 25 years and love them.
This item is perfect for people like me disabled and stayed in bed a lot. It helps prevent bed sores I use it for 35 years and never have problems with it
