What to Compare Before Buying
- Bench dimensions: Compare the 30-inch cushion length and 8.5-inch width with your bench.

- Attachment: Check whether the three Velcro pads and the described bench-seat arrangement suit your setup.
Compatibility, Size and Fit
Size A is the 30-inch version. The source gives conflicting boat-size guidance for this size, so do not rely on a boat-length or model-range label alone. Check your bench dimensions and confirm the correct size for your boat before choosing.
What Is Included
The described configuration consists of the seat cushion and detachable under-seat storage bag. The description does not specify other included items.
Before You Decide
Confirm the cushion dimensions against your bench, the bag dimensions against your storage needs, and the correct Size A fit for your boat. The stated boat-size guidance should be confirmed before relying on it.
