Super comfy pillows! Perfect mix of soft and supportive, and they don’t go flat. Sleep feels way better—definitely recommend 😊

Time will tell
Size: King
I won’t actually use these for a few days when my mattress arrives. Unboxed this morning and they are not as plump and full as I expected but they’re laying out to expand. Overall first impression is they felt comfortable and I could adjust them with my hands. They seem well made and durable. Cant say anything yet about firmness or shape retention since I’ve not used them. They feel like they will be soft. So time will tell but so far I’m loving what I see.

HOTEL pillows King Quality is Great
Size: King
Just got these pillows today. I have never spent dollars on pillows; but I wanted Hotel Grand like the ones that I sleep on in the Hotels and these fit the bill. Large King is what I got and so far so good. Firm and Squishy like I like. I was impressed with the quality -- now lets just give them a few days rest. I am sure they will be GRAND.

Hotel Grand Pillows
Size: King
Very soft, comfortable and fluffy. I’m a side sleeper and don’t feel they go flat. I bought 2 king size pillows. I was initially looking for fluffy feather pillows… but this is the next best thing. I was pleasantly surprised. Turned out to be more comfortable than I thought they would be.
