Good fix for a walker v. buying one with a built in seat.
This accessory fits my walker.  However it has to be disassembled to put in the car or for storage.  Not hard to do, but inconvenient.  The seat is stable/secure and comfortable.  I sat on it for 15 min. while in the waiting area after I got my COVID 19 vaccination.  The second picture shows it partially closed; you have to release the Velcro straps to get it partially closed.  I also have a canvas carry-all attached to the front.
