I have osteo artritis in all my joints and suffer from severe backache. I also have osteoporosis. I wake every morning in severe pain and can feelthe springs in my orthopaedic mattress. I hate it.it's on a slatted base but I think the slats are too far apart but that's all it came with. I am 5'4"and weigh 12st (or at least I did before Xmas and the goodies got eaten. I have not been back to my slimming club since then and may have put on some (oh the shame!!!)please could you advise on a bed before I kill my children for moaning at me about it.
