Slings for fixed ceiling hoist.

Aloha, I desperately need a good fitting sling when hoisted- my legs are very long and the slings I have been given by local authority OT’s literally ride up so high- it cuts me in two!! Ive tried Prism, Osprey, Care Co and still nothing. Im physically getting damaged each time and am one away from being bed bound unless a fitting sling can be found. I need a sling that sits upright and isnt bucket type. Any suggestions greatfully received. TIA

I use an oxford in situ sling, it then remains in place under me while I’m in the wheelchair.
not sure if it makes a difference but I use it with a free standing hoist, not a ceiling one

Thank you Floopy-i will take a look
