Yes and no. I live in Mn. I need cool quilts in the summer and warm quilts in the winter. High loft and poly is definitely warmer in the winter. But, how many do you need? Every family member has, at least one high loft, tied quilt and one low loft summer quilt. Cotton simpy is not that warm if you have drafts, keep the heat down at night or are sick or have health issues that make you feel cold. Poly works by holding in your own warmth. Thats one of the reasons afgans made from poly yarns are so warm. I am now making a round of lap quilts for family members who have health problems because two reported that the warm and natural quilts are not warm enough.

I totally loved joannes soft and crafty hi loft when it first came out. However, by the second year, they cheapened their product and removed much of the loft. Still aggravates me. Anyway, if you want warm, stick with a poly or mostly poly and don't do really heavy quilting. If you want average, use whatever you want. I use a lot of quilters dream and warm and natural and quilt it the way I want, but I use lofty batting(sometimes 2 layers) and wool to tie for very warm quilts.

Edited to add: adding additional quilts if you are cold doesn't work for a lot of people. Either they can't stand the extra weight or they have a physical problem like neuropathy from diabetes. I used to love having two or three quilts on at night and then I got older and find it cloying.
