I am 6'5" with a longer than average back and neck for someone my height. I weigh 16 stones. My wife also is 16 stones. She is 5'10". The base we own for a mattress to go on is a kingsize Dunlopillo pocket sprung base, split top to toe.
What I like in a mattress (although have only ever been able to try in John Lewis, Fenwick etc), is a feeling of weightlessness. Allow me to be specific: what I mean is that if I adjust my position, the springs should adjust with me but not have an 'echo bounce' straight afterwards. So if I am lying on my back and decide to push down with my heels and shoulders, my rear end should lift a few inches and then stay there. And later on, if I want to push down with my rear, it should stay down. Another way to explain is to imagine floating in water, or in space: you position a body in a certain arrangement and it just stays there, without being pushed into another position. I also want to feel enveloped by the springs/fillings - as if I had had a mould made for me.
One mattress I used to own that did NOT do this for me was the Pure Rest Elise - a very high end British handmade mattress using predominantly wool and horsehair on a single spring layer, used on their own sprung base. It felt like there was not enough vertical movement, and my hips ended up sore as they were taking too much weight.
The mattress I liked most was in Bentalls in Kingston and was the Vi-Spring Sublime Superb, one up from the Tiara Superb.
Having said all this, I would pick the Artisan Bespoke 002 in medium. But what I would like to hear from you, please, is what difference YOU think I would notice between this and your Artisan Bespoke and Artisan Luxury models.
Many thanks
