Mangar compressed air products
Mangar have some very useful products.
I have used a compressor that will pump a platform up from the floor, to a seating position, if I have ended up on the floor. The only disadvantage was that the seat was very slippery.
The other Mangar unit I used pumped a pillow up to tip my legs onto the bed, it also makes the side of the bed like a cot side. Preventing me from falling out during the night.
The side drops down very easily by deflating the cushion.
