The "HOTEL'S SELECT" series, developed by France Bed to pursue sleep quality. Special cutting ensures excellent breathability. The low-rebound material provides a gentle, enveloping sleep experience. Compared to the Shoulder Fit model in the series, this one is slightly firmer, but softer than the Regular model. The height differs between the front and back, so you can use it in your preferred orientation (9cm on the lower side, 11cm on the higher side). ■Size (approx.): Width 58 x Depth 35 x Height (max) 11cm ■Material: Outer fabric/100% polyester, Filling/Low-rebound urethane sheet, Pillowcase/100% polyester ■Country of origin: China ■Notes: * Cover can be removed and washed. I used it for about a month, but it didn't suit me, and I've been storing it in the closet since then. I used my own pillowcase, so I didn't put my head directly on this pillow. It's clean, but please refrain from purchasing if you are concerned. Also, I have thrown away the box.
