I had a sleep number type bed and wasn't working for me, slow ait loss over the night and the sides were foam blocks that would bow out, so I decided on a memory foam bed, I have had all sorts of 2 to 4 inch toppers in all sorts of density over the past 10 years and I took a chance on this bed. I couldn't find any info on swiss lux on the net, that is because it is not a swiss lux, the company that makes this uses the swiss lux name probably because it will mess with the sales of their full price beds. When the bed arrived(in 4 days) the only thing that said swiss lux was a piece of paper in the box, the bed has a excellent warranty and the company has been around a long time(sorry, couldn't find the actual name since I am at work). The same exact bed I seen for sale at **** for $2800, so this is a steal. I removed it from the box, turned the heat up and within 2 hours it was it's full size, no issues with smell, they went away in about 1 day. Comfort: the first night I slept on it and felt the same as my sleep number bed on the settings I used to use, but I am no lightweight and I have a bad back, then the next day I had also bought a lambs wool 1 inch topper to go on the new bed from overstock, it arrived and I put it on the bed and now this is my untimate bed, love it. Zero back pains.. Ok to be fair, I weight around 300 pounds, any memory foam bed would have to be rock hard density to support me well, but adding the topper, it reduces my body heat from transfering to the memory foam and the result, is simular to a higher density bed since it doesn't sink as much and supports me perfect. I am 100% satisfied and would buy again, it is a very good bed for a low low price.
