Please be sure to go to the Pillowise app and put in your measurements to be sure that the blue size in right for you before purchasing. Pillowise pillows are similar to Temperpedic however they are not as firm and are measured to your size. I loved my red Pillowise and ordered the blue after inaccurately being fitted. Slept on the pillow for a few nights and then realized it wasn’t for me. I couldn’t return it so if someone fits a blue and wants a lower cost feel free to purchase.
