By far the best mattresses. Immortal, they don't wear out, they don't break, they are worth every last Euro - unlike cheaper mattresses, which start to "wear out" after 10-20 uses and need to be thrown away within 6 months. They are soft, firm, and with the right thickness. If you try them, you won't want and won't be able to go back to the pile of mattresses. For those who complain about slipperiness, a minimal break-in period is needed, after which the stability of the mattress will amaze you.
