Tried lots of mattresses in shops - so difficult to tell what they will be like to sleep on! We tried a version of this mattress that didn't have the pillow top (but still the same 1000 pocket geltex) but hoped it would feel the same! 
Conclusion after a week - yes, feels very comfortable, quite firm. Only thing not sure about yet is the 'coolness' of the geltex. We previously had a memory foam mattress which was very hot and wanted something cooler but with a similar feel. Hoped the geltex would do just that  - not convinced yet! Will see how it goes through the summer.
