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!!
Size: 22 Inch by 22 Inch
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!

King Bed Pillows
Color: White, Size: King (Pack of 2)
I purchased these HKYLRAN King Size pillows for my bed, and they are very comfortable and supportive. The adjustable filling makes it easy to find the perfect firmness for sleeping. They feel soft, fluffy, and hold their shape well. Overall, a great value for a good night’s sleep.
