Comparable to Vispring Stowe Superb?

Please could you tell me which of your mattresses would be closest in feel to the Vispring Stowe Superb? We tried it out and found it really comfortable; we like a mattress that is supportive, but has that 'hotel', luxury feel and soft on top. We have a pocket spring mattress at the moment, and use a thick mattress topper, but would like to invest in something a bit more comfortable. We are 5'9" and 5'7" and 11 and 12.5 stones. My mum bought a mattress from you a couple of years ago and raves about it!
