Designed for Horses With a Flatter Back
The Thorowgood T4 Cob GP MGX is particularly worth considering for horses with a lower wither and flatter back shape.
Its tree and panel configuration are designed to follow a broader, flatter back profile rather than creating a pronounced perched-on-top position. The slim panels provide a closer contact feel, while the wool flocking allows a qualified fitter to make appropriate minor adjustments where required.
However, no saddle should be considered a guaranteed fit based solely on a description. Every horse is different, and professional saddle fitting is recommended before regular use.
Adjustable Gullet System
One of the useful features of this Thorowgood saddle is its changeable gullet system.
The adjustable design allows the tree width to be changed using the appropriate gullet bars, with options ranging from Narrow Medium through to XX Wide.
This can provide greater flexibility for horses whose shape changes over time because of:
- Changes in fitness
- Weight fluctuations
- Seasonal condition
- Muscle development
- Changes in workload
A saddle fitter should determine which configuration is appropriate for your horse rather than choosing a gullet based only on the horse’s breed or measurements.
Wool-Flocked Panels
The saddle features wool-flocked panels, which can be adjusted by a qualified saddle fitter when necessary.
Wool flocking can be useful because it allows the fitter to make adjustments to the panel balance and contact as the horse’s back changes.
Professional assessment should always be carried out before making alterations.
Comfortable General-Purpose Design
The T4 Cob GP MGX is designed as a general-purpose saddle, making it suitable for riders who want one saddle for a range of everyday activities.
It can be considered for:
- Hacking
- Schooling
- General riding
- Riding club activities
- Leisure riding
- Everyday flatwork
Its dual-flap construction, soft knee roll and repositionable knee blocks provide flexibility for the rider’s preferred position.

Condition – Used Grade 4
This is a pre-owned saddle in good used condition.
As with any second-hand saddle, it shows evidence of previous use. The available condition assessment identifies:
- General wear to the seat
- Moderate wear to the left flap
- Moderate wear to the right flap
- Scuffing around the pommel
Please examine all available photographs carefully before purchasing so you can assess the cosmetic condition for yourself.
The saddle’s condition does not replace the importance of having it checked by a qualified saddle fitter before use.
Is This Saddle Right for Your Horse?
This model may be worth considering if your horse has a:
- Flatter back
- Lower wither
- Broader cob-type back profile
- Changing body shape requiring adjustable saddle width
Nevertheless, saddle fit cannot be guaranteed from measurements alone. Your horse’s back shape, movement, musculature and rider position should all be considered.
If you’re unsure, we recommend arranging an assessment with a qualified saddle fitter.
17.5-Inch Seat for the Rider
The 17.5-inch seat can suit riders who require this seat size, but the correct saddle size depends on the individual rider and the design of the saddle.
When choosing a saddle, consider:
- Your height and build
- Your preferred riding position
- Available seat depth
- Knee block position
- Flap length
- Your horse’s back length
If you currently use a different saddle, don’t assume that its seat measurement will translate exactly to another model.
Saddle Fitting Advice
Getting the correct fit is one of the most important parts of buying a saddle.
Before purchasing, consider having a qualified saddle fitter assess:
Horse:
Back shape, wither clearance, tree width, panel contact and saddle balance.
Rider:
Seat size, knee position, stirrup position and overall balance.
Movement:
The saddle should remain appropriately positioned while the horse is moving.
Because this is an adjustable saddle, the gullet configuration and flocking should be selected or altered according to the horse’s individual requirements.
Try Before You Commit
Buying a second-hand saddle online can be difficult when you don’t know whether it will suit your horse.
