The 3 row tip and roll bleachers provide a convenient, transportable bleacher solution. These have a high quality anodized aluminum and welded joint structure that's enhanced with swivel casters and special rubber pads to make the tip and roll bleacher system portable and sturdy. The pads protect all flooring types from scuffs or dents, so the tip and roll bleacher unit is great for indoor or outdoor use. Three-rows of seating will seat anywhere from 15 to 54 people, depending on the length. Tip and roll bleachers are great for flat and hard surfaces or on soft, grassy grounds with ground sill stabilizers.
