Fitted wardrobes offer a number of advantages over traditional free standing types.
Free standing wardrobes tend to have gaps around the sides and top. This can gather dirt and dust over time, which can be difficult to clean. This can be particularly troublesome for those with reduced mobility or allergies.
Your wardrobe is made to suit you, so you have control over what you want. For some this means added rails, others prefer deep shelving. The choice is yours.
Wardrobes can be made to look as though they are part of the room, almost like a wall, blending in seamlessly.
