Comparable mattress to the Staples Mesmerise bed

7 years ago I bought a King Size Staples Mesmerise bed. This has 70mm of Visco-Elastic memory foam with 1200 Pocketed springs and Hypo-allergenic.
This has been an excellent bed and I now wish to purchase a single with similar or better memory foam bed. Staples (Myers) when I phoned to find out what model is now similar or better were not particularly helpful as the person I spoke to said "they did not make memory foam bed"!!
What would you recommend please?
