Park benches are a specific brief: long enough for three, arms to push up from, a back angled for sitting rather than slouching, and construction that shrugs off years outside. This design hits it with seven 2x4s and six 1x6s — a rectangular seat frame with five crosspieces (that's what keeps a 6-foot span from ever bouncing), leg assemblies that carry arms into taller back legs, and stretchers low down to stop splay.
The plan's opening line is the whole quality philosophy: wood glue at ALL joints. Screws clamp; glue is what makes a hundred small joints act like one stiff frame after five years of freeze-thaw. Use an exterior glue and don't skip a joint because it's 'just a stretcher.'
The screw schedule is deliberate too — three per joint where the legs meet the seat frame (the highest-leverage connection), two most other places. Follow it rather than averaging it out. Deck boards go on last with the shorter screws, and the sander earns its keep on the arm tops, which are the part everyone actually touches.

Assemble the two 72" rails with the five 21" crosspieces — glue every joint, two of the longer screws per joint. Five crosspieces on a six-foot bench is the anti-sag budget; space them evenly.
Attach the front and back legs to the seat frame with glue and THREE screws per joint. This is the bench's highest-leverage connection — every sit levers the legs against these screws, which is why this joint alone gets the third screw.
Set each arm on top of its front leg and tie it into the taller back leg — glue, two screws per joint. Check the arms are level with each other; on a bench, mismatched arms read instantly.
Screw the short stretchers between the bottom of each leg pair, glue and two screws per joint. Their job is exactly what the plan says: they stop the legs splaying under load.
Center the 69" stretcher between the two leg assemblies, low, and attach with two screws per end. It ties the ends into one frame — the difference between a bench and two chairs holding hands.
Attach the three backrest supports with glue and two screws per joint — ends and center. These set the back's angle; dry-fit a back board and sit against it before the glue grabs if you want to fine-tune the lean.
Lay the 1x6 seat and back boards with even gaps and screw down with the shorter screws, two per joint. Sand the arm tops and the seat's front edge until they're kind to skin, then finish exterior-grade.
Place it where the afternoon light lands, and accept that it will become the most-photographed thing in the yard.
