Right now to reassemble the seats and the covers,
Start with the backrest cover and put over the back, And pull the holes over the headrest holes from back to front and gently tease the material back under if needed.
When you have done this pull the front down and place the Velcro strips of the seams into the foam of the cushions so it should look like this,
Next you have these 2 plastic strips,
Like so,
Which need to be attached to the two strips of metal indicated and then next you need to place the back of the seat cover into the other side of the black plastic strips that you attached to the seat in the last step.
Like so
Next and you will not enjoy the next step, You have to join these two strips together,
Its a right pig of a job to do and you will more than likely struggle but it is doable. Once together fold over the flap and stick it to the Velcro.
Should look like this now,
Job done.
Base Cushion,
Place the cover onto the cushion and proceed to hook onto the following hooks.
These are the hooks on the front of the base cushion that you need to hook onto with the cover,
Once done find the 2 hooks either side of the base as pic shows,
Now you should be looking at this now,
And you will need to get the corner of the cover and the cord as shown in this pic,
Now pull tight and hook onto tag on both corners at the rear of the seat.
Right, next step is to pull tight the cord and hook onto base of seat both sides as shown in next pic,
Next is too attach the black plastic strip on the metal strip to keep the material taut as shown,
Next just fold under the flap and hook under the seat as it was when you started.
One seat done, Replace all the plastic trim, Picnic table and headrest and replace into car.
Admire your hard work and enjoy the satisfaction that you did it.
