I’ve used the Inserto Mediano cushion listed below for the last two years with no skin pressure issues or problems when transferring.
I had used gel cushions in the past but I find the foam layers in the Inserto offer more stability and comfort especially when sitting for longer periods. The foam requires no adjusting like the gel inserts need for active wheel chair users.
