Accuracy of colour and wood characteristics: whilst we have made every effort to ensure the colours and wood characteristics displayed on our website are as accurate as possible these images may vary from the actual product. Wood is a living material, which swells when moisture or humidity levels rise and shrinks when moisture or humidity levels fall. These not only show that your floor is a natural product but can also lead to some irreversible deformation of the floor if the room climate and humidity is left too high or too low for an extended period of time.
