What's this tartan and what else do you see?

[MacGumerait]

Just an amateur observation .

It would appear that the sett of the tartan on the seat , side panels and arms is a bit different than the tartan on the back .

On the seat , sides and arms the " red block " area is equally sized to the rest of the sett . On the back , the block area appears to be smaller than the rest of the sett .

I apologize if my terminology isn't quite right as I am certainly not an expert in this field .

Cheers , Mike
