Does more filling weight mean the product should be more expensive?
If the product has a higher fill power, it will be more expensive for the same weight of down. When products have a lot of fill and are heavier, they do not necessarily have to be more expensive. The quality of the down fill and the shell material play a very important part in determining the price of a product and quality of a product.
What is meant by thread count?
Thread count is the sum of the warp and weft of the threads per square inch. The higher the "thread count" is the tighter woven the material is. The material will have a smoother and softer feel to it when it has a higher thread count. Covers made of 360 thread count, 100% cotton sateen are the best for goose down filling material.
