GoTo Foam 1″ Upholstery Cushion — 44ILD, Made in the USA
GoTo Foam’s 1″ thickness cushion offers a firm feel with a density of 44 pounds per cubic inch and a compression rating of 44ILD. Made in the USA, this cushion is Certipur certified, ensuring low emissions and a safe foam for marine use. Its compact height makes it suitable for leaner boat seats or shallow cockpit benches where space is at a premium. Ideal for refresh projects where a quick, affordable upgrade is desired, these cushions provide a solid base that can be layered with top-grade marine-grade fabrics for water resistance and longevity. Consider pairing with water-repellent fabrics to boost durability in damp environments.
Features to note: American-made production, Certipur certification, 1.79 density with 44 lb compression, a sturdy option for marine seating rebuilds where firmness is preferred. The 24″ x 72″ footprint allows multiple cushions per order, reducing project complexity for larger boats.
GoTo Foam 2″ Upholstery Cushion — 43ILD, Firm
This GoTo Foam cushion doubles the thickness to 2″, delivering a firmer, supportive feel that is well-suited for boat seating where occupants may spend extended periods seated. The cushion retains a dense core with 43ILD, providing robust shape retention even after repeated use. As with the 1″ option, it is fabricated in the USA and Certipur certified, aligning with health and environmental standards while offering reliable durability on water. This size is compatible with many standard boat seat shells and can be combined with weather-resistant fabrics for maximum longevity.
Durability factors include the 1.8 density and 43 lb compression, which balance comfort and support for adults or children during long rides. It’s a practical upgrade for anglers and cruisers who value upholstery that resists compression over time in marine conditions.
GoTo Foam 3″ Upholstery Cushion — 44ILD, Longer Lasting
The 3″ GoTo Foam cushion supplies a plush, comfortable seating experience with a 44ILD rating and a durable 44 lb compression. Made in the USA and Certipur certified, this option is designed to endure years of use and can stand up to bouncing waves and frequent seat reconfigurations common on boats. With added thickness, it improves seat comfort for long expeditions, while still offering good recovery characteristics to maintain shape after compression. Suitable for bow seats, cockpit benches, and replacement cushions, it pairs well with marine-grade fabrics or vinyl to resist water intrusion and staining.
Expect long wear from this cushion under typical marine use, with an emphasis on maintaining shape and comfort across seasons. Proper installation and secure fastenings help prevent slipping in rough water scenarios.
AK TRADING CO. Scrim Foam 1/4″ Thick — 58″ Wide
This scrim foam from AK TRADING CO. offers a 1/4″ thick foam with a spun-bonded polyester backing, designed to serve as a sew foam layer or backing for upholstery projects. Sold by the yard, it can be cut to fit boat seats or cushions with ease, making it a versatile choice for detailed marine upholstery. The backing provides a smooth finish that helps seams glide through sewing operations, reducing fraying and easing installation. It pairs well with higher-density foams to craft comfortable yet durable marine seating or cockpit pads.
Applications include boat seats, automotive upholstery, RV seating, and various furniture projects. This option is especially valuable for adding a slim layer that improves edge finishing and fabric handling during upholstery work on boats where space is limited.
FoamTouch 1″ Upholstery Cushion — 84″ Length
FoamTouch’s 1″ thick cushion offers a high recovery rate and broad length, making it well-suited for longer boat cushions and upholstery projects. The cushion is designed for resilience, with a density around 1.8. This combination supports comfortable seating and maintains shape through repeated use, while the length accommodates longer bench configurations common on mid-sized boats. It is MADE in the USA and built to last 7 to 10 years under typical use, providing a balanced option between cost and durability for marine applications.
Consider this option when replanning boat seating layouts that require uniform thickness along entire benches or when replacing extended cushions in cabins or cockpit areas. Pair with marine-grade fabrics to maximize water resistance and wind-driven wear resistance.
Buying Guide: Key Considerations For Boat Cushion Upholstery
- Foam density and ILD: Higher density and ILD (indentation load deflection) values provide better support and longer life under repeated use, which is important on boats where cushions endure crew movement and sun exposure.
- Moisture management: Marine environments demand moisture-resistant fabrics and water-repellent coatings on covers to reduce mildew risks. Consider combining high-density foams with marine fabrics to extend life.
- Dimensions and fit: Measure seat depth, width, and backrest angles before ordering. Matching the cushion footprint to the existing seat shell ensures a snug fit with minimal trimming.
- Manufacturing origin and certifications: Look for USA-made foams and Certipur certification for safer off-gassing and lower chemical content, particularly important in enclosed cabins.
- Backing and skins: Scrim foam backs or backing materials simplify sewing and edge finishing. For boats, choose fabrics that resist UV, salt spray, and mildew while maintaining colorfastness.
- Thickness choices: Thinner foams (1″) are budget-friendly and good for refreshed, shallow-seat projects, while 2″ and 3″ foams add plushness and long-term comfort for areas with frequent seating.
- Durability over time: Consider expected usage patterns, such as fishing boats with heavy gear or cruisers with long days in sun, and select foams rated for lasting comfort and shape retention.
- Installation: Use secure fasteners, weather-resistant grommets, and high-quality thread when sewing or re-covering, ensuring cushions stay in place on rolling water and during sudden stops.
- Compatibility with other materials: Ensure chosen foams are compatible with your fabric choices and any vinyl or marine-grade coverings, to avoid abrasion and premature wear.
