Hotel Grand Set of 2 pillows
Size: King
Excellent quality and comfort. The pillows are soft but with the perfect support, ideal for any sleeping position. They feel fresh thanks to the cotton cover and keep their shape very well. Without a doubt, a great purchase for a hotel-like break at home.

Highly recommend

These pillows are super comfortable and feel just like hotel quality. They’re soft but still give great support for my neck and head. I’ve been sleeping much better since I got them. They stay fluffy and don’t go flat, and the material feels nice and cool. Definitely a great purchase

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.
