Quilt and Doonas thickness or
density is measured by 'gsm' (grams per square meter). The thickness of the
filling and the type of filling determine how warm the Quilt and Doonad is.
Generally microfibre
quilts between 150-300gsm are on the thinner side and only suitable for warmer
months (depending upon your climate of course). Quilts and Doonas more suitable for winter
are usually in the 400-600 gsm range if microfiber or wool based, and 700-1400
for the feather based Quilts and Doonas. Feather based Quilts and Doonas can have very similar gsms
even if a quilt and Doonas for winter vs more warmer months because the weight doesn't
change, but the fill type (ie more down than feather) might.
You will also find a
corresponding relationship on price and quality with gsm. Cheaper quilts have a
lower gsm generally whereas more expensive Quilts and Doonad have a higher gsm.
A number of Quilt and Doonas manufacturers also use a 'high loft' (equivalent to 2-3 blankets, 450 gsm),
'light loft' (equivalent to 1-2 blankets 300gsm) or 'super loft' (equivalent to
3-5 blankets 500gsm) rating. This is to help customers in determining warmth
factor. 'Light Loft' is therefore a suitable summer blanket and high/super are
more for cooler nights.
