Due to a bad fall,the onset of osteoporosis and bad arthritis, I needed a new mattress that was deep enough so that I didn't need to struggle to stand up.This mattress is fantastic.I bought depth 27cms which is perfect,also it's comfy.I read the feedback and decided on medium support because I sleep on my sides and my back.Also the delivery men were very sweet and cos I'm wee bit disabled,they put the mattress on my bed for me!!
