    Just ordered my second staircase from Stairbox and couldn’t be happier. Their online design tool is so simple to use. My most recent staircase is excellent quality and so straight forward to install. It arrived within two weeks and was excellent value for money. Great service from a great company.

    I have recently installed a set of stairs from StairBox. They fitted perfectly and were easy to install - Overall I am very impressed with the staircase and would highly recommend this company. Gareth from StairBox was a pleasure to deal with and was very helpful in all stages of the process.
