We need a new bed. The current divan has only lasted about 4 years. You can't so much as cuddle without a loud squeak and the mattress is so uncomfy which is annoying as it's fully pocket sprung. I've been looking at the premier Inn hypnos ones and now I'm getting millions of mattress adverts. What's good but won't break the bank, I need it to be firm ish as I have back and hip problems, but don't care if it's a divan or frame as we have plenty of storage. Recommendations please!
