Very nice quality
Size: 2' x 3' (Sheepskin shape), Color: Creamy White, Size: 2' x 3' (Sheepskin shape), Color: Creamy White
I ordered three of these, and they arrived promptly and very well packaged in a vacuum seal pack. Once you pull them out, shake them and fluff them a little bit they lose their wrinkles pretty quickly. They seem to be very good quality and are authentically sheepskin. The “white” has a tiny little bit of a yellow undertone, which is what I expected since it’s basically a dyed sheep skin. I would call the white color “natural” rather than white white. They are very thick and were a good price. I ordered two of the three foot-long hides and one 6ft foot hide. One of the hides had a slight odor to it that reminded me a little bit of eggs. It’s been laying on my bench all night and 24 hours later there is no smell. The other two hides had zero smell at all. I think it’s just a little leftover chemical smell from the treatment of the hide when they get it ready. It wasn’t overwhelming or overpowering. If you’re looking for the ultimate SUPER plush sheepskin, I recommend the Overland Sheepskin Company. However, for what I need these for which is just something to throw over my dining room table bench for a little cushion and aesthetics. It’s absolutely perfect and the right price point.

Beautiful Good Quality Sheepskin, Beautifully Packaged
Size: 2' x 6' (Sheepskin shape), Color: Creamy White, Size: 2' x 6' (Sheepskin shape), Color: Creamy White
Very nicely packaged and presented sheepskin rug. Seems like very good quality and is just as I imagined it would be based on my previous experiences with sheepskin.
I don’t think it’s as soft as others seemed to think but it has been chemically processed and it is very similar in texture to what I remember from past experiences with sheepskin.
I got this for the kitties to nap on - one seemed proud of me for bringing home a pelt and went into hunt mode. The other looked at me suspiciously like he didn’t really know me at all and was afraid I could be eyeing him for his fur!
Hopefully once they both adjust they’ll enjoy napping on it 🙀😻

Full of beauty!
Size: 2' x 6' (Sheepskin shape), Color: Creamy White
This company takes pride in their work. The sheep skin covering is beyond what anyone could imagine. I purchased this for medicinal purposes. I found out I have SI joint dysfunction. And this sheepskin helps to relieve pressure points so I am using this as a chair covering for when I sit. The product came in a big box and then a plastic bag and then a third, well covered, plastic bag to protect the sheepskin. You will not be disappointed if you purchase this covering. The price was excellent. It will take your breath away. Very happy with my purchase. There was no odor when I opened the package. Many thanks for an excellent product and helping me to be more comfortable when I sit for short periods of time. :)

Nice, but almost feels faux to me
Size: 2' x 6' (Sheepskin shape), Color: Pink, Size: 2' x 6' (Sheepskin shape), Color: Pink
I like it, but it says it’s real, and I believe them, but it feels like it is faux. I’ve owned a fake one before and it feels similar. Please know I am not saying it is not real. I guess the fake was well done!
It’s super long and I am still on the fence if I want it this long. I’ve taken a pic here, but right now it is wrapped in the package in case I need to return.
It is soft and pretty, but I’m not sure that Barbie pink is my best choice lol. Usually I would pair it with a mid century modern bedspread that is chenille, with a little pink so it works well but not too matchy matchy. I wish I had taken a pic with that bedspread because the bit of pink on the bedspread looks very nice against the rug. So let me apologize for having it with an ugly bedspread.
