After researching all the different types and brands of memory foam mattresses, my husband and I decided (after reading the numerous positive reviews) to take the chance and order this mattress. We are very glad that we did! We were a little hesitant because we couldn't find any information on "Swiss Lux" anywhere on the internet but that is because it is actually a "Soft Tex" mattress just under a different, less expensive name. I suffer from bad back pain so we were looking for a firm, supportive mattress. Well, this mattress is just that. It is VERY firm so it provides the much needed support my body requires. We have been sleeping on it for 2 weeks now and have adjusted to it. It does require some time and patience getting used to it, especially if you are coming from a spring mattress. We followed the directions and waited 48 hours before sleeping on it. But within a few hours of opening the mattress it had inflated to its full 10 inches. The unique smell of the memory foam dissipated within a week. Overall, if you are looking for an EXTREMELY firm, supportive memory foam mattress I would highly recommend this one!
