No worries there, simply send us an e-mail along with a few photographs of your furniture and the furniture tag (if any). Typically, differences within 1-2cm (or up to 0.8") are negligible and can be chalked down to minor measurement errors. You may also reach out to us if you'd like a confirmation on how the model is measured.

However, if there is a substantial difference, then this may be a case of product variation or production batch differences and we may have to look into custom-making your slipcovers to ensure the slipcovers are tailored to your furniture.
