We appreciate your honest feedback on your pillow, Oitnbered. The pillow has a cooling gel infusion in the foam and comes with a cooling cover, all designed to dissipate heat and help with temperature regulation during the night. We recommend using this pillow without an additional pillowcase as the pillowcase can trap heat and the pillow comes with a removable, washable cover. As a reminder, you can exchange or return it anytime as part of the Member's Mark 100% Satisfaction Guarantee.
