Sit up comfortably inside your TentBox

The BackRest fits underneath or on top of your TentBox mattress to create a comfortable seat. It’s perfect for enjoying the view, sipping your morning coffee, eating dinner, or watching a film. The top layer is cushioned for comfort, while the non-slip base keeps it securely in place. Best of all, it can stay inside your TentBox even when packed down.

Compatible with: All TentBox models.

Customer reviews

Customers are genuinely impressed by the BackRest, with many calling it a must-have addition to their TentBox setup. Reviews consistently highlight how comfortable and sturdy it is, making movie nights, reading sessions, and morning brews far more enjoyable. The adjustable angle and slim profile are popular touches, with plenty of customers noting it folds down small enough to leave inside the tent when packing up. It comes into its own on rainy days, turning a weather-forced pause into a cosy, sofa-like experience.

GREAT ADDITION TO THE TENTBOX!

This has been a great addition to our Tentbox. Kicking back under the fairy lights (and with the windows open, under the stars). Easily assembled, and gives some additional padding under the mattress
