Ive always seen these floatin around, however with a hefty price tag, So I decided to make my own. I bought a like new real Sparco "Speed" bucket seat from a buddy of mine for $75. With an extra desk chair at home to sabotage, I was able to modify and mount the swivel base to my new Sparco. Hence a new unique and comfortable desk chair for work at a fraction of the price! Whatcha think?
