Tumble Forms Wedges are ideal for gross motor activities such as rolling, tumbling, and walking up- or down-hill. The adaptive wedges provide comfortable positioning for reading or fine motor activities and can be used as an alternative to sitting when a child lacks head control, balance or trunk control. The foam wedges come in several different sizes to accommodate a wide range of user needs, ranging from 4 to 12 inches in elevation. Use one, two or three wedges together with the child in supine to create a variety of positions with varying levels of support. Used in prone, with weight bearing through the shoulders, elbows, or forearms, head raising, and controlled arm and hand movement can be facilitated. The natural incline of the wedge shape helps facilitate rolling skills and trunk rotation. The antimicrobial protection works from within to help inhibit or prevent odors. It also prevents premature coating wear caused by harmful microorganism growth which can occur during normal usage conditions. The non-toxic seamless coating resists cracking and peeling over long periods of time, retains its shape after long-term heavy use, and may be cleaned with a spray cleanser or disinfected and wiped clean. Latex free. Measures 20" x 22" x 10".
