I am allergic to down, so this was replacing my gross polyester-fill, lumpy, synthetic down comforter. I noticed no odor that others have referred to, and it is of extremely high quality. It regulates temperature fabulously, keeping us plenty warm during the winter, as well as cool during the warmer months. I have also come to love it more than down, because even though it is slightly thinner over all, the filling stays much more evenly distributed, making for a very cozy bed! Initially I winced at the price, but it was totally worth every penny.
I ordered this chair out of desperation due to chronic back pain. I sit ALL day, and for the first time since I can remember I sit virtually pain-free now. The transition was a little difficult, but well worth it. I also noticed a difference in my core strength during yoga. I have used this chair for years, and will never go back to a regular one!
