Dull maybe, but it's really getting to me!
We have a bed frame where the mattress sort of sits inside it, iyswim, and a big fairly heavy mattress. Both of which are fairly new and we love.
But putting the sheets on the mattress is like dicing with death. (Huge exaggeration obvs)
I have skinned knuckles and this time a bent back nail that feels like razorblades have been at it 
I lift each corner of the mattress for the mattress protector and fitted sheet, and then push the sides down by sliding my hands between mattress and frame.
How the F does anyone do this without sustaining injury?!
PS, sorry this is banal.
