Hi 

 

That's exactly I was thinking about as there is not much info provided for step 5. Even if we are using pocket holes, that is a lot of weight for 2x4s to lift (considering if 3 people are actually sitting on this sofa) 

Hope to get some assistance on this topic

Does anybody have a feedback on the comfort of having the seat completely flat and the back completely vertical?  I feel that most couches have a slight angle to both the seat and the back...  Obviously that makes construction more difficult, but if I'm going to spend time/money on a project I want to make sure it's comfy.

Thanks!

Hello, I want to build this but with a slant back.  Has anyone tried this?  I made the simple outdoor furniture (loveseat and two chairs) many years ago and I love the slanted back.  Should I adjust the depth of the overall plan and add a cleat to attach vertical boards to create a slanted back?  Any recommendations are appreciated!

Why do I need to buy 10ft length's?

Can I get away with 8th lengths?

My local store only carries 8ft and 12ft long boards.

I have 24.75 cushions, should I build this to 26.25” instead of 25.5”?

My kids (10 and 13) had a great time building this set while on lockdown at home. We painted it all white. Now the challenge is getting cushions. We live in Arizona, so the sun destroys most material that is outside. I will likely purchase cushions that are made from Sunbrella material. Very expensive, but they will last longer.

Loved this plan! Super easy to follow and easy on the wallet. Only complaint is the amount of waste, but not really much could be done about that.
