Seat height adjustment

[babyboxster]

Hi Folks,

Need some help. Just bought an 04 reg 2.7 boxster manual. However, for some reasons the seats appear to be high.

The only electric part of the seat appears to be for the back part and there is nothing on the side to lower the seat altogether.

Any advice on how i can get the seats lowered??? There does appear to be a hole on both seats on the side of them next to the electric button.

Thanks
