A sex bolster is a firm, round pillow, shaped like a big tube. Lots of couples start with the homemade version: a rolled-up towel.
Fair is fair. A bolster is easy to grab, easy to store, and nice under the knees. But it sits on a curve. Push on one side, and it rolls. Usually right when things get good.
That's why shoppers go looking for grip. One wrote they were "looking for one with a non slide finish."
The WildNightX Pillow sits on a flat silicone grip base. It holds on sheets, soft mattresses, even hardwood. There's nothing round underneath, so there's nothing to roll.
