I’ve read many customer complaints about them such as they flatten out, it’s next to impossible to get customer service on the phone to log complaints and lots of trouble when they tried to return them if they weren’t satisfied.
I swear by latex foam pillows. I have used them for decades now and find they are very supportive. Good ones are not cheap but you can often get them on sale at Macy’s. My husband loves his goose down pillow - which was actually two of them combined to get the density he liked. His pillow is substantially more expensive because of that. My advice is that your sleep is way too important to “go cheap” on things like mattresses, sheets and pillows. If you’re not comfortable, you won’t sleep well.
When liberals found out the owner was a Trump supporter they started flooding surveys with bad reviews. They even knocked the company down to an “F” BBB rating. They hate him and would love to have him out of business because he supports Trump. I don’t know that I would believe most of the negative reviews until you try one yourself. I love mine.
