Top quality carpet.
Many twist carpets look similar or talk about weight and don’t always mention the ply.
FW90 Netherton Natural
This one is 2 ply. Many are just 1.
This one has 1/10th gauge rather than 1/8th which is an inferior density
It is rolled in 2m so need 2m through boot to transport.
Very heavy
This is simply left over from carpet fitting.
