Hello, I'm looking for some help choosing an appropriate mattress for my sixty six year old mother. She is a slight and delicate 7 to 8 stone (variable) and 5'4". She suffers from osteoarthritis and back pain. She describes wanting a soft mattress, but she says memory foam is uncomfortable because she finds herself very hot and sweaty in the night on that type of mattress. My mother, like me, has very broad shoulders for her frame, and as a side sleeper I've always suspected that this necessitates a softer mattress?

My budget is basically zero, but with some idea what to look for, I hope to be able to find save and borrow enough to get her something that's suitable for her needs. Perhaps you have something in your outlet area that's suitable?

many thanks for your time >
