Shedding – Shedding is a natural part of the carpet and happens most when it is just installed.
Flattening – Carpets will flatten over time, particularly in high traffic areas. Regular vacuuming helps to reduce this and lift the pile.
Indentations – Furniture feet are the biggest culprit for causing indentations. This can be helped by regularly moving furniture in your room. Some people find using an ice cube and a spoon to lift the fibres to be effective (embed video and reword if needed).
Fading – Wool carpets are particularly suspectable to fading when exposed to continuous sunlight. This is common during the summer months. This bleaching can be reduced by using curtains and blinds to limit the amount of direct sun your room gets.
