## Questions & Answers

**Q: Will my mattress smell?**
A: It’s quite normal for new mattresses to have a slight odour when they are unpackaged, however, it is nothing to worry about and by airing the mattress you will find that any odours will pass.

**Q: Is settlement normal?**
A: Your new mattress is zoned to complement the human body and it is the underlying support system that ensures you are offered optimum support in the zoned areas.  Some settlement in the filling layers is perfectly normal, there is no need for concern.

**Q: Can I clean my mattress?**
A: We always recommend using a mattress protector which you wash on a regular basis along with your sheets. Using detergents or chemical cleaners on your mattress may damage the fabric and stitching. Your mattress cover is not suitable for washing.

**Q: Which sleep accessories are best suited to this mattress?**
A: The Silentnight Deep Sleep Pillow, Duvet and Mattress Protector complements the mattress perfectly, offering great comfort for a snuggly night’s sleep.
