Start small... go big!  With this simple outdoor sectional piece plan, you can make an outdoor sectional as big (or small) as you need, as your budget or schedule allows.  Build a couple sectional pieces this year, add on next year - the options are endless.

Easy to Build Corner Piece

It's easier than ever to turn corners!  We've updated the plans so all you have to do is add an arm piece to the basic sectional piece to create corners for your sectional.

Standard Outdoor Cushions

Each sectional piece (including the corner) fits a standard 25" x 25" deep seat cushion, up to 5" thick.  For corners, you may need two back pillows.  

If you purchase the cushions in sets with both backs and seats, consider purchasing another set, and using the spare seat cushion on an ottoman.

I don't know how you do it! Amazing. Now I wish I wouldn't have bought those four chairs for my screen porch. This could have doubled as a sleeping porch now that its getting warmer.

We have been trying to find something that would work for our screened porch. I think we just found it. Thank you so much!

A couple comments on the cushions. There are different types of foam - make sure if your sectional is going to be outside (not inside a screen porch) that you buy OUTDOOR foam. It cost more, but it will dry quicker and will not mold or rot after repeated times getting wet and air drying. Same with the fabrics. If it will be outside, invest in outdoor fabric. Regular "indoor" fabric will mold rather quickly and will fade and wear out from sun, wet, dry, weather.

The cheapest place to buy foam is from ebay. Do a search for it and you will find many places that sell it. I bought 2 types of foam (harder foam and memory foam) off ebay and made my own tempurapedic mattress last year. The whole thing cost me about $200 as opposed to a $1200 tempurpedic mattress.

Also, if you make cushions, make sure you add zippers. They do take an extra step, and there is the cost of the zipper, but when your cushions get dirty and you want to wash them you will be happy! Otherwise you will have to take them apart to get them off and then when you wash them that edge you had to take apart will probably fray and you will have a hard time putting them back together (I am telling you this from experience!!!).

Love the plan though and can't wait to see a finished project.

Wow, this looks fantastic! I love how thoughtful you are with your plans (like making sure we could all get the best deal on the cushions).

Thank you thank you! And one question for anyone who makes this or owns something similar: Do you think it would be comfy enough for frequent indoor use? I'm debating between something like this vs. twin daybeds to replace our living room sofas. I'm guessing a solid back would make it more comfortable. This sectional is beneficial over the daybed because it's more narrow and would save some space.

Great plan! I'm also thinking about making this for my living room...we need a new sofa really bad! Can't wait to see if someone else does it first though :o)

I have a giant giant patio with nothing on it because putting out a table and chairs would look ridiculous. So: Aaaaaaaaaahhhhh!!! Thank you!

How would you recommend keeping the pieces together so they don't slide all over the porch?
