Hi I've been doing a lot of research and keep coming back to your helpful site! Our king size mattress has done us well for many years but we've now made the decision to replace it. It's on a good divan base. We are a middle aged couple (56 and 59) in good health, my husband weighs 12 and a half stone, I weigh 10 and a half. We both prefer a firm mattress. He's a back sleeper and can sleep anywhere. I'm a side sleeper and have been having problems sleeping since hitting the dreaded menopause last year - night sweats and also hip pain waking me up. I've looked at your Origins 1500 and Artisan 1500 but can't decide which one. Either way my husband says he would prefer firm tension, but would this be too much firmness for me? Any advice appreciated!
