Just thought I’d share this small victory - I look after my Grandad who’s 91 and for the last 18 months he’s been really struggling to get out of bed in a morning, he has terrible dizzy spells first thing which lead to frequent falls. He’s had various tests, tablets for vertigo and nothing worked.
We had a visit from a new Occ Health physio and she suggested raising his pillows so he’s more upright at night, I was like yeah… surely that won’t work but we’ll have a go… 
what do you know, 2 weeks in and a massive improvement in his morning dizzy spells! 
Now all I need to do is work out how to stop him fidgeting so much and chucking the pillows on the floor during the night 
You could try putting the pillows (one, some, or all) underneath the bottom sheet, or use a third sheet (round the wrong way) if there’s not enough left to tuck in. 
Genius!! Thank you!!
