Nice pillows
Size: Queen, Number of Items: 2
Have had these a few months and so far really like them!
They don’t really feel very cooling, but I also run VERY HOT so it could just be me. The foam holds up well and hasn’t flattened like others I’ve tried.
They come very compacted- I was shocked how much they expanded!

Love them!!

Ok I normally don't leave reviews but I had to on this pillow. I was looking forever for a pillow and was nervous about buying one because you know how that usually goes when it comes to buying pillows. They arrived compressed but when you unwrap them they blow up to be a heavy duty pillow. Firm but not too firm. I don't like super soft pillows that you can roll up in a ball with one hand, I like a pillow that gives support and these do just that. They are cooling as well they are pretty for a pillow with the unique design. If you are in the market for a pillow and reading this THEN BUY THIS PILLOW & come back to tell me thank you. I promise you will NOT be disappointed. No I didn't get paid to say any of this. I wanted to give a honest review where it deserves one! You will not be disappointed! Thanks for the fast over night shipping as well. Not to mention the pricing is on point. I can say right now you will not find 2 pillows of this quality & price.
