Very firm pillow
Size: Queen (Mid Loft), Number of Items: 1
I'm not sure I received the same pillow as advertised. The pillows I received are extremely firm. I would not classify it as medium. It was also not covered by a cotton case. it had a very sheer gauze like material covering the latex.

Super springy and comfy!
Size: Queen (Mid Loft), Number of Items: 1, Size: Queen (Mid Loft), Number of Items: 1
I’ve been looking for a pillow that offers support but is soft and cushy. I had never tried a latex pillow before, and I was skeptical because I heard it could be hard, but I decided to give it a try. I tried a memory foam and it was waaaaay too hard to be comfortable. This pillow retains its shape, is really soft and plushy, and works great for back or side sleeping. It had a slight smell (not unpleasant though) when we first unboxed it, but it was gone by day 2. The pillow also sprang up immediately on unwrapping it. After a few days it seemed a little bit bigger, but it didn’t really need any time to air out/fluff up, it was basically ready straight out of the box. I’m often picky about pillows because I get headaches from sleeping on my neck in the wrong way, but this one is great and I haven’t had a problem at all. My hubby likes it too :) it’s the favorite house pillow now.

Sleeping like a dream!
Size: Queen
We stayed at a Westin hotel recently and usually I don't sleep well when traveling but this overnight stay was heaven! I don't know what magic is in these pillows but they are a dream! I sleep in my side and these are perfect, I sleep the entire night with no back or neck issues. I've tried some expensive pillows from Sealy, Serta, etc, and nothing compared to the Westins! So glad these are available through the Westin Amazon store! And less expensive than anything else I've tried.

Not the same as hotel pillows.
Size: King
Ordered this pillow after staying at a Westin hotel. I should have returned it because it seemed different from the pillow at the hotel. It feels worn out and doesn’t keep its shape. Would not recommend.

Big high pillow, firmer than expected.
Size: Queen
This pillow could be a 5 for some people , and it was a 1 for us. Too high for our neck. Side sleepers. It’s probably very good for a back sleeper.
