A recent study conducted at Georgetown University showed a 10.9 percent increase in standardized achievement scores when learning environments went from "poor" to "excellent." Designed by Shawn Barrett, Intellect Wave classroom desks provide exceptional comfort and permit a certain degree of movement that results in improved alertness and learning retention. Intellect Wave classroom desks include several styles - cantilevered, 4-leg, tripod, two-student, chair/desk combo and double entry. Standard desk tops are 26" x 19", while ADA desk tops are 33" x 20". Desk tops provide a variety of storage options, including a plastic book box, wire book basket and book bag hook. The chair/desk combo and double entry desk offer a wide, passive flexing back and waterfall seat form to lessen pressure points and increase comfort. An integral handle enables easy movement. The ribless design of the seat shells is easy to clean. Engineered to withstand tough classroom use, Intellect Wave desks exceed industry standards for durability. Elliptical tubing provides superior frame strength. Lightweight, textured poly shells resist scratching, fading, chipping and denting. Hard plastic or laminate tops provide a durable worksurface. Intellect Wave desks are made in the USA and backed by a 15-year warranty.
