The Bumfire Heated Seat Cushion – Warmth Wherever You Sit
Sitting outdoors and still staying warm – that’s exactly what we designed the Bumfire heated cushion for. Whether at the stadium, while camping, on a park bench or your balcony: simply connect a standard USB power bank and the cushion heats up to a comfortable 37–39 °C. No mains cable, no complicated switch – just plug in and feel the warmth.
How the Wireless Heated Cushion Works
- Connect a USB power bank – the cushion heats to 37–39 °C
- Disconnect the power bank = cushion off. No switch needed.
- 5,000 mAh power bank = approx. 2–2.5 hours of warmth
- 10,000 mAh power bank = approx. 4 hours of warmth
- Overheat protection is built in
Built Tough, Designed Smart
The Bumfire heated cushion is made from water- and dirt-repellent outdoor material, carefully handcrafted. Compact and lightweight, it folds in half and fits into any bag – secure it with the elastic band or carry it on your wrist using the loop. Wipe clean with a damp cloth. Due to the permanently built-in electronics, the cushion must not be washed.
Black/Red/Yellow – Show Your Colours
The Bumfire heated cushion in Black/Red/Yellow is a bold, tri-colour design that stands out in any crowd. Perfect for sporting events, festivals, or any outdoor occasion where you want to make an impression. The striking colour combination turns your seat cushion into a conversation starter – all while keeping you warm for hours. A statement piece for those who love colour. Also available in Black/Red and Black/Yellow.
