Buying Guide

USCG approval matters

Choose cushions labeled as Type IV or USCG‑approved if you want an approved throwable flotation device for boats

Cushion vs. throwable function

Decide whether you need primarily a seat cushion for comfort or a dual‑purpose cushion that doubles as a throwable rescue device

Material and comfort

Look for weather‑resistant foam and covers that resist mildew and UV exposure for longer comfortable use on deck

Visible color and safety extras

High‑visibility colors and built‑in whistles increase findability in the water and add a simple safety benefit

Fit and portability

Check dimensions and weight so the cushion fits your seats and is easy to move or store when not in use
