These pillows are amazing. I absolutely love them. I’m going through menopause, so I’m constantly hot, then cold, then hot again. These pillows are truly cooling, and they make a huge difference. I’m a side sleeper, and they are incredibly comfortable. They’re worth every penny, and I highly recommend them to everyone.
