I used to have leg and foot cramps in bed nearly every night.
I would end up walking around the house for 15 minutes
to get rid of the cramp.
So for the past 3 months I have been placing a kitchen chair at the foot
of my bed and I drape the bed covers over the chair, which then forms
a tent for my feet and legs.
Now the bed covers don't put any pressure on my feet and legs.
I have not had a cramp since, seems the bed covers were too tight
