Fits the window seat like it came with the house

Measured twice, ordered once. The trapezoid cut for our bay window seat slid right in — edges are clean and the HD36 foam doesn't flatten after months of daily reading. The spec sheet that ships with the box is a nice touch.

飘窗垫严丝合缝，像原装一样

量了两次尺寸一次下单，梯形裁切正好嵌进转角飘窗。HD36 海绵坐了几个月没有塌陷，随箱附的规格单也很专业，切的就是你订的。
