Love it, but terrible smell at first
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
Really soft & my dog loves it. I used it as a throw over my couch for decor. The smell when I took it out of the package was probably one of the worst smells I’ve ever smelled. Like old broccoli or something. I left it outside to air out all day and that was gone.

Not premium quality! I've seen actual authentic ones before.
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
Despite all the positive reviews, I believe this product is subpar. There are genuine sheep skin Hydes but this product is NOT it. There is no leather embossing showing authenticity, and many signs of strong chemical treatment. Smell is lingering and I've aired them for over two days. Not very comfortable since the fur is very thick and coarse, you would expect it to be softer for the price as well. Not premium quality. I ordered this for my children to sleep on at long evening Church services but now I will look to more niche sellers for a higher quality product.

Great product: thick and cozy
Size: Single Pelt/2 ft x 3 ft, Color: Natural (Ivory Whiite)
This is a lovely, thick sheepskin. I’m using it to drape over a chair. It’s very soft. The color is a natural white. Arrived quickly. The price was great for such a wonderful sheepskin.

Love it!
Size: 2' x 6' (Double Pelt), Color: Linen, Size: 2' x 6' (Double Pelt), Color: Linen
Exceeded all expectations. Bigger than I imagined it would be, super soft and thick, beautiful color (Linen), and no funky smell at all. It seems very durable. After running my hands all over it, no shedding occurred. I have yet to sit on it myself, though, as my cat claimed it right away - didn't even wait for me to remove the tag! He's been there for hours and I'm thinking I've lost my snuggle buddy, so I bought two more in the smaller size so he can have his own on the bed with me at night. I am so amazed by the quality, feel, and color. I can't believe I almost let other reviews deter me from this purchase. 100% thrilled with this beautiful pelt. Absolutely recommend!
UPDATE:
I received the other 2 purchased. Just as soft, just as thick, consistent color (Linen), no shedding, no smell. They have been in use for several days now without any issues. Love them all - and my snuggle buddy is back! 🥰
