Hello, I have a budget upto £ 1000 to buy a mattress - width 180 cms x length 200 cms. Could you pleas kindly recommend an option from your Artisan range ? Where can I try out your mattresses in London. I don't live in England so my trying out options are rather limited. I will be visiting London in 2 weeks time so I could perhaps visit one of your retailers. Thank you very much for your help. Kind regards, Margo Mirgos
