I’ve struggled with finding the right pillow for years. Last year I bought the casper hybrid mattress and it was soooo comfortable. When I started frequently waking up with a stiff neck I decided it was time to find a new pillow. Previously pillows have always deflated overnight leaving me flat on the mattress but the hybrid pillow keeps it’s shape all night long. I am a predominantly side sleeper but have found it to be comfortable in all sleeping positions and no more morning neck pain!
