Step 1: Pallet deconstruction time.
Tools you will need:
Back up Hammer
Disassemble the pallets, keeping in mind that many long boards will be needed.
Disregard the base parts of the pallet, they have too many nails in them and are not worth the effort to keep unharmed.
If you lose your patience with removing the pallet wood, simply use the jigsaw and cut the boards at each end, then play around with it until the middle of the board comes unattached.
Step 2: Cutting out pieces of the frame
At the tip and butt of the piece, there must be a crevice, so that the next piece can fit in snugly and be supported on i.t
Step 3: Cut that and multiple pieces
repeat until you have 4 pieces.
Then make eight of those pieces and connect four of them like below
Step 4: Glue the pieces together
Make sure to screw the boards together as well. With 2 on each side of the joint.
Step 5: Put supports in between the two main frames
And put them on the bottom to about the second support.
drill in 2 on one side
remove clamp on that side
drill in other two
remove that clamp and move on to the next board
Step 6: Get very nice cushions
Can be bought from costco. Preferabley weather resistant
40$ for both of them.
