Oak narrow 2 Shelf Part of our oak stacking range, the oak shelves are available in modular units that allow you to customise the organisation to suit your space. The flatpack assembly means they're simple to construct and adjoin, and can be used vertically or horizontally, or even as a room divider depending on the space. ‐ Dimensions: W 42 x D 28.5 x H 81.5cm Add‐on shelving units can only be attached to the side panels of a base unit. Please note, a stand‐alone base unit cannot be expanded upwards when placed vertically and cannot be expanded sideways when placed horizontally.
