How to Make a Diamond Quilted Seat Cushion for an RV Dinette

In this tutorial video, we will show all the steps required to make a box cushion with a diamond quilted/pleated top plate. This cushion also includes a boxing that is continuous, meaning it has no seams on the front two corners. The cushion replaces a cheap seating cushion that was purchased for an RV dinette. Our cushion will utilize high density foam, which lasts much longer and won’t bottom out compared to a cheap low density foam. Use Sailrite’s Fabric Calculator to easily calculate the amount of materials required for your cushion. It also calculates the measurements of your plates, boxing and zipper plaque for your particular box cushion's desired size.

This is exactly the video i was looking for. Thank you so much, excellent Chanel

[@stoneblue1795]

Always some inspiring stuff. I ordered some doo-dads and supplies from you guys this week, thanks!

[@stevenjackson5543]

Never thought I could do this until I started watching your videos and I did my whole pontoon boat and it came out beautiful you are a awesome teacher

[@SailriteDIY]

Thanks! Good job!!!

[@m.serdargokhan4220]

Very good video, thanks

[@jmu3551]

Eric is the best, what a great teacher, so easy to follow and products suggested are totally worth the investment

[@stanleycarranza6440]

Espectacular

[@sswcustomsewing4276]

Thank you 👍

[@SkylinersYeti]

loving the instructional videos. I have a travel trailer that has foam cushions that are too soft. Also the cushions do not match the lids for the storage below. I want to make firmer cushions that match the underlining storage lids. I have ordered foam samples and need to have my wife pick out fabric. Thank you.

[@SailriteDIY]

That's great to hear! It's awesome that you're customizing your travel trailer cushions. I'm glad the instructional videos are helpful for you! Let me know if you have any questions, via [e-mail]

[@haroldpramekamol1009]

This was such helpful video! It was succinct and direct. My first project turned out great. Wonderful tips. I just got my LSZ-1 the other day. Great performance and easy to use. I like the whole package.

[@SailriteDIY]

We are so glad you like our video and also the Sailrite Ultrafeed LSZ-1 Sewing Machine. Keep sewing!!!!

Is there a video showing how to make the zipper plaque/pocket so it falls completely along one edge instead of wrapping around as shown here?

[@SailriteDIY]

Yes, here is a link to that tutorial video: kzbin.info/www/bejne/an6uoqGggsx8pas

[@laszlomonse6721]

Is there a way to calculate how much fabric is needed if we use this diamond pattern with 5mm thick foam? The backrest of my boat is 4.5m long, so there are lots of diamonds to make, which would require more fabric... but by how much? Thanks

[@SailriteDIY]

When sewing diamond quilted panels I usually make the panel about 3 inches winder in length and width than the desired finished size. I hope this helps.

[@carlyk3675]

If we are doing a 1/2 inch seam allowance, shouldn’t the fabric cuts be 1” larger?

[@SailriteDIY]

We want the cover to compress the foam slightly which is why we do not add the seam allowance.

[@carlyk3675]

@@SailriteDIY ahhh ok, Ty for quick response! I’ve got all my sailrite supplies ready to make new cushions but was confused about the seam allowance. Thank you for the informative video!

[@jos9569]

I believe the zippered area is a PLACKET, not a PLAQUE.

[@SailriteDIY]

At Sailrite we call the boxing with a zipper a "zipper plaque". (Note that this use of the word “plaque” is not to be found in any dictionary - it is a term created by Sailrite to serve where no other was currently available. The word “placket” is commonly used to refer to a flap of fabric that covers a closure device over a slit opening - so there is some justice in our usage.)

[@scottbryant9425]

wow that's a whole lot of uneccesary work to make a decent zipper
