I am 90Kg and my wife is only 54Kg. We currently sleep on a firm mattress which my wife hates and I've come to like. We have bought a new king size bed with sprung slats and are looking for a new mattress to go on it.We went and tried a few mattresses in store figured out a split tension mattress worked well for us. The following two mattresses we liked:The Vi Spring Bedstead Distinction Medium/Soft (way over budget)The Somnus Marquis Regular/FirmWe spoke to somebody in your office and the initial recommendation was the Artisan Naturals, though I'm not sure if that is comparable to the ones above. He was kind enough to explain that the Artisan Bespoke 004 and 002 will provide a more premium feel. Is it possible to expand a little as if we buy from your company we'll have to buy the mattress without trying it out.
