For the longest time I had uncomfortable and restless nights' sleep.
I remember having a metal frame bed and the most uncomfortable mattress in all the land. You could feel the springs through the material - it was horrendous. I used to have to carefully position my ribs between them to make myself comfortable and to not have anything digging into my body.
Alongside being a boney little rascal, I also suffer with a bad lower back, leg pain at night, and more times than often I wake up with a bad neck/shoulder from awkward sleeping positions.
