Hello. I wonder if you could give me some advice? I weigh about 9 stone 5 and currently don't have a partner (although I wouldn't rule that out!). I have a bad lower back and also a lot of neck pain so I'm looking for a matress that will not exacerbate these problems and ideally one that will help. I tend to be very cold when I first get into bed (and in winter use a hot water bottle or an electric blanket) and to use a warm duvet etc. Having said that my new bedroom is in the loft space of a tiny open plan house with a wood burning stove so it should be very warm up there in the winter. I'm on a tight budget but on the other hand chiropracter visits are expensive so I want to buy wisely. I've been recommended a 4000 pocket sprung matress with 'zero gravity' foam. I wondered if this is necessary given my circumstances or whether there are better alternatives?? Thank you in advance for any advice you can give. Suzi
