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.

Best pillow I’ve ever tried—hands down!

Size: Queen, Number of Items: 2

I’ve gone through a bunch of pillows over the years, but this BETU Cooling Pillow is by far the best one I’ve ever used. I sleep in literally every position—on my back, stomach, and sides—and this pillow works perfectly no matter how I’m laying. It really does have a cooling effect, which I love as a hot sleeper. Just make sure your room is cool too, and it makes a big difference. It came vacuum-packed, but it fully expanded within just a few hours. I was able to sleep on it the same day it arrived, and it was super comfy right from the start. I also washed and dried the pillowcase before using it, and it came out looking and feeling great—no shrinking or damage at all. Honestly, I look forward to going to bed every night now just because of this pillow. It’s supportive, comfortable, and totally worth it!
