Seachoice White Foam Flotation Cushion, 15×15

The Seachoice White Foam Flotation Cushion is a square, 15 by 15 inch throwable device built from foam padding. It is designed as a Coast Guard approved Type IV throwable flotation device, with nylon construction and either US-made or imported origins. Best for boaters who want a compact, readily accessible throwable safety aid that also doubles as a spare seat cushion in emergencies. A potential limitation is its small size for larger passengers or long, seated sessions.
Seachoice Blue Foam Flotation Cushion, 15×15

The Seachoice Blue Foam Flotation Cushion mirrors the white version with the same 15 by 15 inch footprint and nylon build. It is also a Coast Guard approved Type IV throwable flotation device. Best for boats needing a color option to coordinate with deck styling while keeping trusted safety standards. Choose this if you prefer a blue accent in your gear kit; note that color does not change performance.
Boat Throwable Flotation Cushion (Yellow, 2-Pack)

This yellow 2-pack offers dual Coast Guard approved Type IV throwable cushions for boats over 16 feet. It functions as both emergency throw devices and extra boat seat cushions, making it ideal for larger boats or families needing multiple flotation options. Best for safety-conscious owners who want redundancy. A potential caveat is that the cushions are primarily designed for emergency use; as seat cushions, comfort depth may be less than gel seats.
NEW-Vi Anti-Slip Kayak Seat Cushion

The NEW-Vi cushion uses a double-layer gel design to provide maximum support and comfort for sit-in kayak seating. It is described as waterproof and thicker than traditional cushions, aiming to prevent numbness and reduce lumbar strain during long paddling sessions. Best for kayakers who spend extended periods seated and need improved pressure relief. A limitation is that gel cushions can be heavier and may require occasional care to maintain slip resistance.

Buying Guide
- Safety first: Look for Coast Guard approval (Type IV) for throw cushions intended as safety devices. This ensures compliance with marine safety standards.
- Intended use: If you need emergency flotation, prioritize throw cushions; for long-duration seating on kayaks or dinghies, choose gel or thicker cushions.
- Material and grip: Anti-slip surfaces and water-resistant fabrics improve stability on deck or in a sit-on kayak.
- Size and fit: Consider whether a 15×15 inch cushion suits your boat’s seating area or if larger options are needed for taller passengers.
- Maintenance: Gel cushions offer comfort but may require care to maintain cushion integrity; fabric-only throws resist wear but offer less comfort for long sessions.
