Tried out the buy one get one free offer and were not impressed. We've actually gone back to our old pillows.
The customer service was difficult to use and is the reason why these were not returned. The representatives would always say they would contact you back. The claim that they would give us better sleep did not come to fruition for us. The pillows seem to be too stuffed and do not allow an alignment of the neck as advertised.
The travel pillows that came with the offer are great supports for your lower back while sitting.
Thank you for your time. Peter Bushnell
