We are slowly (very slowly) making our way through the outdoor pieces with cushions to accomodate less expensive cushion options, and today’s plan is our next victim! We covered the matching Free DIY Furniture Plans to Build an Outdoor Reef Chair with Modifications for Cushions from Target and now we do exactly the same for the sofa!

The cushion options here that will work best are either the Threshold Outdoor Cushion set or a less expensive option is a combination of the Outdoor Deep Seating Cushions and Outdoor Back Cushions.

  1. I really like this plan for a sofa and the reef chair. I’m having trouble looking at the pictures. Is there a PDF link I can download? Thanks in advance! Btw you have an awesome collection of stuff to build!

          1. Yes!! Just in time for the weekend too! This is probably my favorite site right now, thanks for sharing all these great ideas!

  2. Do your cushions overhang the front of the outdoor sofa? I am looking at 24″ x 24″ cushions and not sure exactly how to modify the plans to fit them.

    1. i actually just updated the cushion links for this plans so you can get dimensions for them. no the depth of your cushions is the same as the cushions i used to draft this plan. the only difference is that yours are 2″ wider. so in theory all you need to do is add 2 inches for each cushion, to all of your horizontal boards (probably 4 inches total). this would likely mean one additional back slat and your spacing would change a bit, but if you just space them evenly you will be good to go!

  3. I really like this pattern but I’m considering making it so that it accommodates 4 of the target cushions. Would you recommend adding an additional leg piece?

  4. Hi,

    Good plans. Can you make sure the required lumber is correct? After adding up all the cuts, it will take more than 5 2×4’s complete according to the cut list. Also, for the 1×4’s, you are using actual 0.75″ x 3.5″ lumber?

  5. Hi I know this is an older post but probably a silly question. I’m doing all the cutting ahead of time and wanted to know for the back slacks are those 16 3/4 on the shorter side (the 25 angle) or the loger side of the board?

  6. Beautiful plans! Thank you.

    Do you have an approximate weight for the couch, chair and armless chair? Just curious how heavy they are.

  7. I made the sofa and it came out great. I used pressure treated deck boards for mine ripped down to 4 inch. Should last a long time! Materials cost me $100 from Lowes. Thanks for the plans!
