New Boat Upholstery, Repair Boat Seat Cushions & Yacht Interiors.
There's more to marine upholstery than foam and fabric. The method of stitching, for example, can make a big difference in water resistance, performance and style.
When fabric is simply draped over the foam it's called waterfalling. This method is sleek and keeps the water out, but the edges are rounded.
Top stitching allows for crisper edges and a cleaner look. A top stitch is extremely strong, but not waterproof. A wayward stitch is sort of like an upside down top stitch. It's not waterproof, but the seam is pointing down so it drains better. The wayward stitch is used in many marine applications.
A French stitch looks like a baseball seam. It allows the fabric to lay flat. Some like the way it looks, but it's the least water resistant stitch so you don't see it on boat decks very often.

How Not To Build Marine Cushions
Every once in a while we come across a real head scratcher; these boat cushions, for example.
They're fabricated with Ez-Dri® foam. Ez-Dri is perfect for boat cushions. It's manufactured with stiff polyurethane and extra large cells. Instead of absorbing water the way most cushions do, this stuff is engineered to promote drainage; water goes right through one side and out the other. Matched with a quality marine fabric such as Sunbrella, an Ez-Dri cushion drains in no time. And since there's plenty of air circulation, they tend to stay fresh.
Original Boat Cushion
Plastic Under The Cover
The people who made these boat cushions wrapped them in waterproof plastic, evidently to keep the foam dry. Maybe you can see where we're going with this. Ez-Dri is designed to soak up and discharge water. Covering it with plastic defeats the whole purpose. Instead of draining water, the plastic allows water to pool under the fabric. Plastic covers create the perfect environment for mold and mildew.
Ez-Dri & Dacron Layer
And that's not the only thing wrong with these. The white material covering the foam is Dacron®. We use Dacron all the time. It's an excellent way to soften a cushion. It gives the cushion more body, a little bit like a pillow. The thing is, these cushions were built with the Dacron on the bottom instead of the top. It doesn't do any good on the bottom.
It's a good thing they brought these in. Before building new covers we cleaned and re-engineered the cushions so they perform the way they're supposed to.
Glue-Down Carpet For Boats
In addition to marine upholstery and boat cushions, we install custom snap-in and glue-down carpet for any size pleasure craft. This 19 foot Bayliner Capri illustrates how it's done.
The process begins with the boat owner selecting a replacement carpet. The owner could have gone with an entirely different look – there are plenty of alternative styles and colors available. Instead, he decided to stick with the original rubber-backed burgundy.

Bayliner Capri After New Carpet
After sizing the replacement carpet, we strip the old flooring, scrub and prep the fiberglass deck, then begin the actual installation. This is where experience is all important. The carpet needs to be a perfect fit because there's no floor molding to cover frayed or misaligned edges. What's more, this sort of flooring doesn't stretch the way standard carpeting stretches. You have to get it right the first time.
Why We Don't Use Cheap Fabrics
Customers occasionally ask why we only use marine grade fabric when upholstering boat interiors and cushions. The pics below help illustrate why. The first two show a standard grade red vinyl purchased by a customer to reupholster his boat cushions. The vinyl looks and feels great, but look what happened when we stitched through the material.
As you can see, the vinyl chipped around some of the thread holes. Adjusting thread tension didn't solve the problem. The vinyl face and thin backing on this fabric simply couldn't cut the mustard.
Standard Grade Vinyl
Marine Grade Vinyl
After seeing the problem, the customer agreed to use the marine-grade vinyl we recommend (second row). It looks and feels the same, but the vinyl is more durable and the backing is sturdy. Sewing this fabric into cushion covers was a breeze — the stitching turned out perfectly.
You'd think the better vinyl would cost more, but not in this case. Our superior quality marine grade vinyl turned out to be less expensive. So, be sure to contact us before buying lousy fabric from somebody else.
Our craftsmen fabricate marine cushions with the finest materials. Even using the best foams and fabrics, wrinkles are inevitable. Eliminating wrinkles is one of the biggest challenges we face when fabricating custom marine cushions. Steam is the best way to get the wrinkles out. Here's how we do it.
Quality In Every Detail
Generic boat cushions are easy to make. Premium quality, custom-fit boat cushions require the skills of a maritime upholstery craftsman. Here's an example of how pleasure boat cushions manufactured by Mac's are superior.
We only use durable, marine grade vinyl
Using two Velcro bands instead of one ensures cushions stay put even in rough seas
Seams are meticulously stitched using heavy-duty thread
To maximize air circulation, we drill a series of precision vent holes in the back of the cushion
Gusseted zipper pockets keep the zipper slider in place
Our premium quality upholstery foams and marine foams perform years longer than standard foam
Recover Grady-White Cushions
If the owner of this Grady-White had waited any longer to fix the onboard cushions, it might have been too late. As you can see from the first two pics, the vinyl was already ripped to shreds and the foam was deteriorating.

After replacing the bad foam with good stuff, we covered the repaired cushions with superior quality marine-grade foam. The pleated backrest for the aft bench seat would've been difficult for some shops to recreate, but our craftsmen are the best in Seattle. As always, the reupholstered marine seats turned out great.
Bolstered Marine Cushions
Bolstered marine cushions are among the most difficult to upholster, especially when they're long and contoured, such as these from a Yamaha speedboat. Not only are these cushions difficult to pattern, you have to find a fabric that's both tough and easy to stretch.
Cushion With Sharp Curves
Wrinkled Fabric Before Steam
Steam Smooths The Fabric
Spradling Vinyl has pioneered a fabric with a specially engineered flexible backing. It's called Softside™. Durable and easy to shape, it's ideal for upholstering contoured cushions. There are nearly 300 colors and patterns available. The boat owner selected Zander Pearl Grey and Zander Ivory.
Cushions Upholstered With New Vinyl
Even using the perfect fabric, upholstering a monster cushion with sharp curves can be challenging. It requires the right combination of elbow grease and steam to smooth out the wrinkles. In order to keep the upholstery looking good, you have to make sure the fabric tension is evenly distributed. That's where years of experience comes in handy.
Beneteau Sailboat Settee
You're not going to find a more striking example of new upholstery transforming a run-of-the-mill salon sette into something extraordinary.
Compare the original starboard settee from a 42 foot Beneteau Sailboat (insert in large picture below) to the new one. Look closer and you'll discover subtle design improvements, beginning with the seat decks.
The original seat decks were manufactured the standard way, with flat polyurethane foam. Instead of doing it that way, we built a sturdy foam ridge along the lip. This smartly upholstered foam ridge not only cups an individual snugly into the seat, it lifts their legs a couple of inches, reducing lumbar strain. The back cushions are either contoured or angle-cut for optimum confort.

Notch For Armrest
Support Bar Notch
Rather than snap fasteners, we used velcro. Velcro allows more flexibility in cushion placement. Notches in the cushions to accommodate an arm rest and a mast cable bar are engineered to fit like a glove.
As always, we use only the finest marine-grade foams and fabrics. For this settee, the boat owner selected striking Mediterreanean colors from Sunbrella's marine fabric collection.
The new settee is snug, looks great, and fits the salon perfectly. And thanks to our design improvements and craftsmanship, it'll last for years.
Using Design To Fight Mold & Mildew
Seattle's damp climate encourages the growth of mold and mildew. When you factor in all the nooks and crannies found aboard boats, controlling mold can be real challenge. And as mentioned in the section below on Pink Stain, mold is not only unsightly and destructive, it can be a health hazard.
A dry environment is the best way to prevent nasty mold and mildew. But, this is the Pacific Northwest. Good luck keeping things dry.
Mold & Mildew Collect In Seams
Redesigning Cushion Cover
Sleek & Sanitary
Another approach is almost as effective; eliminate places where mold spores and grime collect, such as deep seams in certain types of boat cushions (above left). Instead of simply recovering these moldy tri-panel cushions, we redesigned them. By removing most of the seams, the freshly upholstered cushions not only look sleek, they now resist mold and mildew.
Pink Stain Is Dangerous
Pink stain or "pink mold" is a common problem faced by Northwest boaters. The micro-organism that causes the slimey pink film commonly found on shower curtains and boat cushions is actually not a fungal growth, but an airborne bacterium -- Serratia Marcescens.
This stubborn "pink slime" bacteria colonizes moist environments such as bathrooms and boats. It's also a problem in medical facilities where it causes a number of hospital acquired infections. In brief, pink stain is not only ugly, it's dangerous.
We can help. When fabricating boat seats or cushions, the marine upholstery experts at Mac's Upholstery take specific preventative measures designed to discourage pink stain from contaminating your boat upholstery and seats.
If this nasty bacteria ever does appear on your boat cushions, you'll have to keep them dry and disinfect on a regular basis. Reupholstering the cushions the proper way may be the most practical, long term solution.
If you're considering new boat carpeting or marine flooring, you might want to check-out a new product called Infinity Luxury Woven Vinyl®. This stuff is truly amazing. It's not only beautiful, soft and flexible, but extremely durable. It features a unique, heavy-traffic rated backing system ideal for indoor and outdoor use.
This fabric is UV stable so it resists fading. Antimicrobial technology prevents bacterial growth. Soil and stains are easily cleaned reducing the long term maintenance expense compared to other floor covering options. We've posted pics of the current fabric collection below and we have samples at the shop. Here's a link to the manufacturer's website. Definitely worth looking into as a better alternative to marine carpeting.
