Modular sectional pieces can be arranged and rearranged for different seating arrangements. Make a giant bed for movie night, or individual chairs for a party - these individual pieces give you so many options!
This is a DIY plan to use 2x4s and cedar fence pickets to build the modular sectional pieces. This plan is designed to work with 24" x 24" cushions, but can be easily adjusted for different sized cushions.

- 24 - 1-5/8" or similar length star bit exterior appropriate screws (GRK or SPAX or similar brands)
For the table/ottoman

- 8 linear board feet of - 5-1/2" wide x 6 feet long cedar fence pickets (not dog eared)
- 20 - 2-1/2" star bit exterior appropriate screws (GRK or SPAX or similar)
- 16 - 1-5/8" or similar length star bit exterior appropriate screws (GRK or SPAX or similar brands)
For the chair/single seat
- 2 - 2x4 @ 23.5" - Back legs
- 2 - 2x4 @ 12" - Front legs
- 2 - 2x4 @ 23" - Sides
- 3 - 2x4 @ 20.75" - middle supports
- 6 - Cedar fence pickets @ 23 3/4” (two 6’ pickets cut equally)
For the table/ottoman
- 4 - 2x4 @ 12" - legs
- 2- 2x4 @ 21" - sides
- 3 - 2x4 @ 20.75" - middle supports
- 4 - Cedar fence pickets @ 23 3/4", (6’ cedar fence picket cut equally)
Cut the boards using a circular saw or a miter saw.
If using a circular saw, cut with a straight edge with the board to cut elevated in four points (two points on each side of the cut) or supported by styrofoam.
If you have a miter saw, it is easier to cut with it.
Instructions
Step 1
Attach legs to sides with two 2-1/2" long self tapping star bit screws per joint.
For the ottoman, all is flush to top of legs and to the outsides. Note the ottoman sides are 21" (not the same length as the chair sides - see next diagram).
For the chair, the front legs are flush to top and outside. The back leg is attached so the top of the side is 12" from the bottom to match the front legs. You can use a front leg to mark the attachment point. Make sure you build the chair pieces in mirror as shown in the diagram.
