I have ordered many of these pillows and loved them! Nice and squishy but didn’t flatten like down pillows. I needed a bunch for Airbnb but they are very pricey. Was reading the reviews and several said that the pillows had changed. I thought, how much could they have changed? So I went ahead with purchase. I felt like I may as well have gone to Walmart and bought a cheap foam pillow. Update: finally tried the pillow myself. Although there is a definite difference, it is very soft and fluffy. Changed my rating from 2 to 4 stars.

Throw pillow

The 16” pillow fit perfectly in a 14” case. Filled every corner completely. Would buy it again.

Good quality, inconsistent shipping.

Size: 26 Inch by 26 Inch

Very good quality & fair pricing. Deliveries were challenging as you can order a maximum of 3 pillows per order. I had to cancel a back order & reorder. Not a big deal but required additional unnecessary follow up on my part.

Love!!

The “influencers” are right about these! They are full, fluffy and keep their shape! If you like the pillow chop look, they do it! These are sold as one pillow and more expensive than others but you get what you pay for!
