Hypervent Fights Condensation

hypervent paddingCondensation is often a problem inside pleasure boats. How many times have you found excessive moisture under a bunk mattress or seat cushion? Dangerous mold and mildew thrives in this sort of environment. Hypervent padding improves air circulation and helps eliminate excessive moisture on boats and yachts.

sunmark Color-Matching Boat Cushions

Not all cushions in a pleasure craft wear at the same rate. For example, if family or guests prefer sitting in the stern, those seats wear faster than cushions elsewhere. Since there's no sense reupholstering all the seats when only some are damaged, the challenge becomes choosing a vinyl that matches the color and texture of the original fabric.

It's not as easy as you may think. Take the color white, for example. White comes in scores of shades and tones. Some are a little more "blue" than others. Some appear slightly warmer. It's sort of like the difference between fluorescent tubes and standard incandescent bulbs; the light from both are "white", but you definitely notice the difference.

    Flawless Cushions

We carry hundreds of vinyls and acrylic-based marine grade fabrics. We'd be happy to suggest a color and pattern to reupholster a boat cushion, but ultimately the customer makes the choice. Whatever the choice may be, you can be sure that any boat cushion reupholstered by Sunmark will be durable and flawless.
