Review on Command Pilot Skwoosh Gel Seat Pad - Lightweight, Waterproof, Foldable Cushion With Mesh Fabric And Handles For Travel, Pilots, And Office Comfort by Yolanda Jones

I bought this because the size looked right for airplane & bus travel. I don't want to lug anything too heavy or bulky. But there is a cost to that - it was just too hard. This might be fine if you just need a little bit of extra cushion, but if you are looking for sciatica relief over a long period of time, I don't think this will do it. It is lightweight and it is going to fit in small seats. Another downside to that -- if you have a larger posterior, you might not be happy with the narrow width.
