"simplicity is the ultimate sophistication"  -L. Davinci

When I discovered we could make a lounge with our table legs, I was super pumped. It's solid and stylish.

Our most popular table leg converted into a Lounge Chair.  Using wood and our 90 Degree Bracket and some ingenuity, you can have an elegant, solid lounge chair that you won't see anywhere else.

Step 1:
Purchase your H-Frame legs, 90 Degree Brackets and Cushions

For this build you will need to purchase two 25"H x 36"W H-Frame legs. You will also need six 90 degree brackets. Two of those will need to be 18", two of them 12" and two of them 6". You can purchase these in same finish or mix it up for a unique look. You will also need 3/4" hex head self-tapping screws to attach the brackets to the legs. For cushions, I opted for zipcushion.com. I purchased 24 x 24 x 5 seat and 24 x 18 x 5 for the seat back. These took around 14 days to arrive.

Step 2:
Prep your wood

For the lounge I used plywood and dimensional Select pine boards from Home Depot.

3/4" Plywood cuts: Seat: 24 x 24 Seat back : 18 x 23

Select Pine Boards:

Arm rests x 2 : 1" x 6" x 32" Upper horizontal back rest support x 1 : 1" x 8" x 33" Lower shelf x 1 : 1" x 10" x 24" Lower vertical support : 1" x 8" x 24"

Cut, sand and finish these as you like.

Step 3:
Attach your 90 degree brackets

First, Fasten your 18" brackets to the H-Frame cross bar to create a rail for your seat to attach to. Line the bracket up flush with the bottom of the crossbar 3" from the front edge of the H-Frame on both legs.

Second, attach your 12" brackets 2" from the back edge of the legs. These brackets will support the lower shelf.

Third: attach your 6" brackets perpendicularly 1" from the top edge of the H-Frame on what will eventually be the back side of the chair. These 6" brackets will hold your lower vertical support on the back side of the chair.

Step 4:
Attach your wood

First, Attach your 24x24 seat.

Second, attach your lower shelf 1" away from your seat. This 1" space is crucial, this is where your seat back will sit on the exposed rail(bracket).

Third, attach your Upper horizontal back rest support.

Fourth, attach your lower vertical support to the 6" brackets. This should square things nicely and should feel pretty solid by now.

Lastly, attach your arm rests.

Now you can place your 18 x 24 back rest into the 1" space on seat rails and rest it on the horizontal back rest support. This is meant to not be attached .
