Kayak seat for SUP board AQUASTIC AQS-B4I186-BK with bag black (AQS-B4I186-BK)
AQUASTIC kayak seat is a practical accessory that easily transforms a classic SUP board into a comfortable, recreational kayak. It provides back support, greater comfort while paddling in a seated position, and allows for rest during longer trips. It is an excellent choice for anyone looking to diversify their water experiences and enjoy greater versatility during active recreation.
High backrest – full back support
The model is equipped with a higher-than-standard backrest, which significantly improves comfort, especially during extended periods of sitting. Stable spine support reduces muscle tension and lowers the risk of back pain, appreciated by both beginners and experienced SUP users. This solution genuinely increases comfort while paddling.
Comfortable materials – a combination of EVA foam and polyester
The seat is made of durable polyester and filled with EVA foam (ethylene-vinyl acetate). Polyester is resistant to moisture, mechanical damage, and UV rays, ensuring durability even with frequent use. The internal EVA foam adapts to the body, providing softness, proper support, and thermal comfort, keeping the seating comfortable at all times.
Ideal for long trips – comfortable rest
AQUASTIC allows easy switching between standing and sitting, giving the user a chance to rest and recover during intense water sessions. It is a great solution for longer routes where getting ashore is not always possible. Paddling in a seated position engages different muscle groups and relieves the legs.

Easy assembly – 4 mounting points

This system allows for seamless switching between standing and sitting, depending on conditions and fatigue. Installation and removal are intuitive, enabling the user to adjust the board to their needs in just a few moments.

Practical bag for small items
At the back of the backrest, there is a zippered bag, perfect for storing the most essential items – keys, documents, phone, or wallet. The pocket's location ensures easy access without the need to get off the board, making it an extremely functional accessory during any water adventure.
