Foam bag seat

Hi

I run both my strikers with no drivers seats I use the floor as I am tall and I feel like I am squashed into much in the jk seats I have

So I am going to fit a bag foam type seat and wondered the best kit and place to buy and also the size I will need



Thanks

When making your seat, it is best be be wearing what you intend to drive in most of the time, including shoes/boots to get the correct let relief and pedal width fit.
DO NOT use cheap bags. Unless you like wearing 2 part foam

Having looked around for a suitable strong and correctly sized bag, I picked a Gelert survival bag.
1800mm tall and plenty wide enough.
£4 from ebay
let this hang for a few days in a warm room to remove as many creases as possible.
Fold down the first 800mm and place into the seat position.

Lots of companies make two part foam, I chose CFS.
1 x 2.5kg tin of part A
1 x 2.5kg tin of part B
£33
The larger tins were ordered to allow for the extended leg relief area.
I still have around a kilo of each remaining afer finishing the seat.

You will also need a good sized measuring jug, mixing bowl and wisk. £5 the lot from the Factory Warehouse.

It is important that Parts A and B are kept warm prior to starting to mix. Keep the tins in the airing cupboard for a few days prior to the job. That way, when mixed, they expand much better.

Initially pour 1lt of Part A into the bowl and whisk well until aerated

Having put on your old overalls it is time to go for it and add Part B to Part A and wisk thoroughly.
You will know when it is ready to poor as it turns milky white.
You then have around a minute before it really starts to react and slowly expand

On the first pour you are looking to complete the base.
Once you have estimated the rate of expansion, mix up a further batch of Part A and Part B.
I used 1kg for the seat and around 0.5kg for the back.

Do not get out of your very warm seat during this period, leave the mix and the pour to your assistant.
Once happy withe the rate of expansion in the base, lean forward and have the assistant pout in the liquid for the back.
Once it starts to react, lean back and it will expand around you.

This is the best bit. But first.................
Ensure you have enough tea, biscuits, and ciggies to keep you going for a around a 30/40 minute sit.

As the foam reacts, try to remove as many creases as possible from the bag, an understanding assistant is required for removing creases from the gentelmans areas

Once the seat has cooled down, biscuits and tea consumed, ciggies smoked, it is time to extract yourself gently from what is starting to feel like a very comfy seat

Once you have the seat out, place it on your charming assistants potting table.
Tape the spine protecting tool box foam securely to the seat

Before taping up the seat, trim as required and cut out the holes for the crotch strap mounting bolts
Next apply yards of gaffer tape.
When taping ensure that the tape is put on the sides vertically.
If horizontal it will peel off with repeated climbing in and out.
I dont have much left out of the 4 x new rolls I started with.
4 x rolls £24

One very comfortable and supportive seat.
Total spend £66
Weight of seat 3kg
