## Questions & Answers

**Q: is the stuffing sewn in pockets or in strips in the duvet? thanks**
A: Hi, The one I have is in 5 stitched down strips which vary in size. The two outer ones are approx 30cm and the three middle ones vary from 43 to 46cm. These run the full length of the bed. Warm duvet for 10.5 btw. Hope that helps.

**Q: Is this 10.5tog duvet warm enough in the winter with no heating in the room?**
A: We turn the heating right down at night all through the winter. We set the temperature to not drop bellow 12*c. The radiator doesn't kick in at all during the night. 
I personally feel cozy warm using this duvet in that temperature range.

**Q: Can this be washed at 60°C in the washing machine?**
A: According to the washing instructions attached to the duvet, the answer is NO. only 40 degree's. I always have mine dealt with by a professional laundry.

**Q: Does this duvet comply with bs5867 part 2, bs55815 part 3 and to bs7175 source 7.**
A: Silentnight is an excellent make. So it must comply with all the regulations set out for products of this type. If you are concerned I would email Silentnight and they will answer any queries you have.
