I've been looking for that specific hotel feel without spending a fortune, and these Serta pillows nailed it. They are categorized as medium-firm, which I find perfect, they have that initial plush softness when you lay down, but they don't flatten out completely by morning. The 400-thread-count cotton cover feels high quality and breathable, so I haven't dealt with any overheating. I'm a side sleeper and my husband sleeps on his back, and we both find them super comfortable. If you want a pillow that balances support with that cloud like luxury these are a great pick.

Decent

Color: White, Size: Queen(Pack of 2)

They are only used as a backup pillow for my special pillows I use since I have pillows with holes in the middle for my earrings. I also use them for when I lean on my headboard to watch tv. I like them they are squishy. Kind of expensive I feel like but not terrible

I love these pillows

Color: White, Size: Queen(Pack of 2)

Very good pillows, comfortable and with that hotel style. They have medium firmness, so they work well for any sleeping position. They feel fresh, of good quality and do not crush easily. Excellent purchase.

Worth it, I have 2

Style: All Season, Size: King

Soft, good material, I like the thickness. Does not feel cheap.You do have to put it in a dryer on really low to fluff it up. Check it after 20 minutes. Pull it out fluff it up and put it back in the dryer. Do not use hot heat. I also put it in a linen duvet.
