These anti-slip cushions have been a great addition to my summer water activities .They are portable, lightweight, and versatile, making them perfect for outdoor use. Based on my observations, the cushions provided excellent grip and stability, allowing me to enjoy a variety of water sports and activities comfortably. However, they aren't as large as I would like, but this really doesn't affect my overall experience. I definitely recommend these cushions to anyone looking for reliable cushioningSee full review
