Why is there a distinct odour coming from my new mattress?

Whilst for some this can be a little unpleasant, it is entirely safe, normal, and to be expected. It is also amplified to some degree, as the mattress has been vacuum-sealed and packaged. This is however one of the major factors in Ergo Flex being able to provide such a high specification mattress at a very competitive price. Newly manufactured visco-elastic foam has a distinct odour that will dissipate over a short period of time when exposed to air. To expedite this process you can remove the outer cover and machine wash whilst airing the mattress for a day or two prior to use. We find however that the majority of customers will use their new mattress on the first evening of receiving it.
