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.
The Versa Inserto Mediano is a highly adaptable modular postural positioning cushion for users who need moderate/high positioning support, particularly those who require good lateral, anterior/posterior containment of the pelvis.
It consists of several foam layers with 16 or 17 modular and configurable inserts as standard. It has a removable Incontinence Air Exchange cover. The manufacturer states that this cushion is suitable for those at high risk of pressure injuries.
