Horrible Bed

This has been a guest bed in my mother's house for a couple of years, and so it is nearly new. I am now living with and taking care of my mother and have had to use this bed for several months. It has taken a huge toll on my body. I am quite fit, trim and healthy and careful about the pillows I use, and am aware of how important a good mattress is. I will change this bed as soon as I find something else for the guest room. My siblings complained about it along the way, but I was never on it long enough to notice....until now. My shoulders and neck are stiff, my hip joint is sore and I toss/turn all night long to get comfortable.
