Price Quotes & Ordering:

To generate a boat cushion quote, all you need are your dimensions and to click on a shape below.

You will need to select what type of boat cushion foam you are interested in. Outdoor foam is great because it doesn't absorb water, drains immediately, and lasts a long 10 years. FloTex is a firm certified flotation foam. Natural latex foam comes in several firmness choices. It is an all natural foam and resistant to mold and mildew. It should be ordered using standard size blocks or you'll pay a premium for custom cuts below. Memory foam is a great top layer for comfort but needs to be used with a firm bottom foam layer for support. Both memory foam and regular foam cost less than natural latex, but are synthetically derived byproducts from oil.

If you have questions or need help, please call one of our sales professionals at (415) 503-1188 to help assist you in building the boat cushions of your dreams!

Preparing a Pattern:

Most boat cushions will match one of the shapes above and will not require a pattern.

To begin, take a minute and review how your existing boat cushions look. This is your chance to correct any gaps and make improvements. Next, using paper, plastic, or fabric to make the pattern, simply cut your pattern to the exact sized desired. The more precise the pattern you provide will result in a more exact fitting boat cushion. Please mark on your pattern "This side up" and which side(s) should be used for zipper placement and stripe direction. Keep in mind that most large v berths work best with a zipper wrapping around three sides. Always mark the pattern for zipper placement on the hull side.

For a price quote, use the pattern shape and enter in the largest dimensions (thickness, length, and width) from your old boat cushions.

Beveled Edges:

We can add a bevel to your boat cushions to match the contour of your boat. Simply enter the dimensions of the top (larger dimensions) after choosing one of the shapes above. Do your beveled boat cushions require a pattern? Read the beveled pattern procedures ...

Save Money on Your Boat Cushions:

You can save money by cutting foam for v-berth boat cushions using less foam.

If you were to simply cut your boat cushion pattern from a large block of foam it would start like this. Since you pay for foam by volume, if you use less foam, it will cost less.

V-Berth Cushion

You can save foam and cost by laying the v-berth boat cushion pattern out like this. Only use the larger top pattern if there is a bevel. The center cut out will be seamed together. Always separate each half of the v-berth mattress pattern by 1.5".


A bevel is added and the final cut boat cushions look like this.

Prevent Wrinkles:

A lot of old 1970s shag fabrics were so heavy that you didn't need to worry about wrinkles in the material. Boat cushions covered with lighter fabrics such as Sunbrella ® and micro fiber are thinner and show wrinkles.

There are two ways to reduce and eliminate boat cushion wrinkles.

  1. Without changing any of the dimensions, add a polyester batting wrap to the top and bottom of your foam. This is the most effective method. It also adds a breathable layer between your body and the foam.
    ...Or... (Don't do both!)
  2. Reduce the thickness of the case by 1/4". This option just reduces the amount of wrinkles present.

Customer Satisfaction Guarantee:

Most foams may be exchanged if you don't like the density you have chosen. See exact details during checkout.

Boat Cushion and Mattress Maintenance:

Boat interiors are frequently moist. This moisture gets trapped between your cushions or mattress and the boards below. To help avoid problems with mold or mildew, air your mattresses or cushions outside in the sun every couple of days but don't remove the covers. When you are not using your boat, store your mattresses or cushions vertically in the aisle. For added protection, you can sprinkle anti-fungal powder (found in most drug stores) on the platforms below your mattress or cushions, as well as on the bottom side of the cushions.
