Small Travelwedge
Works as described it's heavy pvc so I pump it most of the way and put it under the hotel mattress. So much better than it slipping out from under you.  Pump is slow and fiddly you have to hold all the pieces together for the 5 mins requred to fill it.  If the nozzle was integrated into the pump it would be a lot better.  But for a travel wedge it does the job well.
