How to Make V-Berth Cushions

Item # X-HT-200620

Does your boat’s v-berth have cushions that are old, uncomfortable or unsightly? The v-berth cushions on our Islander 37 project boat were all three! So we set to work making new cushions that would be comfortable and stylish with a snug fit. In the next video in our Boat Cabin Makeover Series, we’re going to break down all the steps for making brand new, irregular shaped cushions for your v-berth.

DIY V-Berth Cushions

V-berth cushions, with all their angles, can be an intimidating project to undertake, but once you start sewing, you’ll see that they assemble just like any other box cushion. The trick to getting irregular cushions just right is careful patterning and attention to detail. In the video, we break down the patterning steps slowly with calculations, so you’ll know just what to do for great fitting cushions.

We chose to make our v-berth cushions with a breathable Sunbrella® Upholstery Fabric, which is great choice for boat interiors because it is water and mildew resistant. Since the cushions are not reversible, we used a cushion underlining fabric for the bottom sides of the cushions. This helps with breathability for a comfortable night’s sleep and is budget friendly.

In this video you will learn in detail how to pattern both the foam and the fabric for v-berth cushions and how to sew the cushions together. There’s also a bonus discussion on foam and which types best suited for sleeping berth cushions.
