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.

Sleep like in heaven. Every cent worth
Size: Queen
First time a slept on that pillow was on a trip to D. C. and we stayed in a Westin hotel. The best quality of beds, mattress and pillows I ever had!!! On the next morning I told the receptionist how great I slept and they told me, it’s to order. And the funny part is, they called “heavenly”

Gave it 6 month trial before review
Size: Queen
I find it hard to believe these pillows are what is used in the hotels. I like Westin hotel pillows, but they are heavier than this particular pillow. I have used it for 6 months, now it flattens out and just feels like lightweight fluff with no support. It was good for about a month. I try to fluff it up every night to give some lift but I feel this will be thrown away soon. The search goes on.
