Get it right the first time
Two questions decide almost every seat purchase. Will it fit the car, and will it fit you. Everything on this page exists to answer one or the other. Start with your car, then narrow by your own size, then work out the brackets. If you get stuck at any point, ring us rather than guessing.
Find your vehicle guide first, because it tells you whether your car takes side mount or base mount seats and that decides which half of the catalogue you can look at. Then narrow by waist size. Then check the bracket compatibility chart for the brand you have landed on.
Start with your car
In that order. Doing it the other way round is how people end up with a seat that will not physically go through the door.

Shop by driver sizeFour waist bands covering 28 inch up to 42 inch. Narrowing by size before you narrow by looks saves the most common mistake we see.Shop by waist size

Measure your waist over the clothes you actually drive in, not the number on your jeans. If you are on the boundary between two bands, come and sit in both.

WillansTracking your order
Shortly after ordering you get an email and an SMS with your five digit invoice number, the invoice and an estimated delivery time. Quote that number if you ring us about the order.
We use Aftership for tracking, which puts every GSM parcel into one list with push notifications whichever courier is carrying it. It is free and it has no adverts. That matters more here than on most stores, because a single order can leave three different warehouses on three different couriers.
The full picture on delivery costs, lead times, oversized seats and pallet delivered roll cages is on the delivery page.
Quick fire questions
Will I fit in the seat I like?▾
Every seat we list is a different size and shape, and two shells tagged with the same waist range will hold you completely differently. If you are unsure, ring 0115 9893488 and CallyAI will take your height and your waist size and talk you through it. Better still, book into the showroom and sit in four of them.
Will the seats fit my car?▾
Bucket seats are universal by nature, so none of them are compatible with your original equipment on their own. What makes one fit your car is the fitting kit, and that is chosen per vehicle. Find your car in the vehicle guides, or send us the make, model and year and we will put a package together.
How do I know whether I need side mount or base mount?▾
The fitting kit decides it, not the seat, and which kits exist depends on the car. Side mount seats bolt through the sides onto a subframe and sit lower. Base mount seats bolt through the bottom. The two are not interchangeable, so settle it before you buy a shell. Your vehicle guide will tell you which routes your car has.
Do I need a harness for a track day?▾
Usually not, and a badly mounted harness is worse than the standard belt. It depends on the organiser, on whether the car has a cage, and on whether you are running a HANS device. We have a guide that goes through the circumstances properly.
My FIA seat has expired. What are my options?▾
FIA 8855-1999 seats are valid for five years from manufacture, extendable to ten in total with the manufacturer. If yours is out and you are still competing, you need a new one. Bring it in or send us a photograph of the label and we will tell you where you stand and what the current dating is on the replacements.
Can I get VAT relief on a seat?▾
If you are replacing a wheelchair seat or you qualify on disability grounds, yes. The declaration forms are on the VAT relief page and the reclining ranges from Auto Style, Cobra, Corbeau and Recaro are the ones people usually end up in.
When were you established?▾
Garreth set the business up in 2003 from his bedroom, and it has been growing ever since. It is still family run, which is why you get the same two people every time you ring.
Where are you located?▾
Nottinghamshire, in the Midlands, just off the A46. That puts most of the country within a couple of hours. The showroom is by appointment, Monday to Friday, 10.00am to 4.00pm.
