Hi Ann,
So I have had some success with the bed management system with one carer turning. It is basically a system that stays on the bed and the sheets etc are made on top of it. One doesn’t need to take it in and out… its always there ready to be used. Its two very low friction surfaces which allow the person to be moved easily with one carer in any direction. It can be used alone or with a ceiling or a floor hoist. Floor hoist slightly more planning getting the hoist in position over the bed but basically the hoist provides the power to aid a turn. The system has a slide-on brake which means when one doesn’t want the client on the low friction surface it can become a regular surface. Its used in combination with positioning wedges to support someone in side lying
Check it out here.. probably best explained via a video. This from the English suppliers.

My understanding is that yes indeed people do still require regular turns even if on air mattresses.
