Compact Enough for Carry-On Bags: Unfolded: 15.8" × 15.8" / 40 × 40cm - spacious enough for comfortable sitting. The cushion strap holds it neatly closed so it does not come undone inside your luggage or backpack. 600D Oxford and PE Foam-Built to Last: The printed foldable seat pad uses 600D oxford cloth on top for surface durability, a PVC oxford base for stability on smooth and rough surfaces alike, and a PE foam inner layer that provides cushioning. Easy to Clean and Long-Lasting: The oxford fabric surface and PVC base of this printed sitting cushion wipe clean with a damp cloth after muddy outdoor use. For a more thorough clean, hand wash gently and air dry. Closure for Neat, Secure Folding: Two quick folds and a wrap keep this printed seat cushion flat and compact during transport. The cushion holds firmly without bulk, and unfolding takes seconds when you arrive at your seat on the plane. The Travel Companion That Fits Every Seat: Hard airplane seats, stadium bleachers, wooden benches, and rocky rest stops all feel noticeably better with this printed foldable cushion in hand. A great gift for frequent flyers, outdoor enthusiasts.
