Too hot on memory foam!

My research has brought me at last to your amazing website which is so packed full of information my poor brain is going to burst!!

I'm getting less and less sleep ( only 2 or 3 hours a night) with present arrangements, so we need a better 'sleeping platform' asap or I shall go mad. I, 5ft6in 10stone, and husband 5ft 7 in and 11stone are in our early sixties and getting more joint pain, myself more neck and shoulders, husband back pain (old injury). We have tried a memory foam topper, which is very comfortable, my husband loves it, but for me the trapped heat under my body makes me feel as if I'm being griddled alive, even though we have An Outlast mattress protector on top ( which makes no difference as far as I can see). We also tried a wool topper which smelled awful and fell into creases under us, was still far too warm and brought back husband's back pain. An expensive mistake. Our duvet is already only tog3 and even at that I end up throwing it off half the night!

Bedding and nightwear is cotton. So, we despair of finding a solution and would be very grateful of any helpful suggestions you might be able to come up with for a combination of mattress and topper. We have a King slatted wrought iron framed bed. I'm not looking to spend money just for a prestige name, but will spend what it takes to get a decent unbroken nights sleep. Hope you can help!
