Your comparison to the Feather and Black Harrogate mattress?

HiI stumbled across your website whilst doing some research. My wife and I have been into Feather and Black today and liked their Harrogate mattress. We are interesting in purchasing a ZipandLink SuperKing. Having gone through your website, I see there is a lot more to understand about mattresses and I'm glad having done a little research that I didn't get sucked into placing an order with F&B - the sales man I can pay today and get myself in the queue and change options later.Anyway, i would like to find out what you would recommend as an alternative to their Harrogate mattress.
Look forward to hearing from you.Kind regards
Zed
