The customer service of this company is brilliant. I had an adjustment that needed to be done due to the factory's error but the staff of this company were incredible and came all the way to my house to help me fit new pieces. Incredible service, lovely team!

Excellent Service Turned up at office during day as a retail customer following a recommendation. Been looking for an office chair for home office type use for some time. Multitude of chairs to try to find what works best for you. Received excellent service from Bob (and team) to help narrow down the options. Never felt hurried. Kept up to date at all stages on delivery having chosen one. Happy owner of a very comfy chair.

I bought the KAB K4 chair (which, by the way, is life-changing) and received unrivalled customer service - despite being a consumer rather than a business I received such personal service from Dave with calls and texts as the order progressed and a delivery date was agreed, and again after delivery to make sure everything was ok. Would highly recommend Wave Office for consumers not just businesses

Our new first choice for office furniture Amazing customer experience even for a relatively small order. From the 1st call to delivery, Andy and the team were very helpful, responsive and knowledgeable. If only more companies could be like this. The sort of service that means they will always be our first choice for future purchases.

Faultless customer service. Every question I had about my prospective order was answered in a friendly and efficiently manner (no matter that as a retail consumer I may not be Wave Office's target audience) and ordering and delivery were equally effortless and prompt. Definitely recommended.

Brilliant office furniture experience Wave Office have been brilliant during our office refurb. We went into their showroom to find some office chairs and come out with furniture for our whole office. Friendly staff with great communication and everything was delivered/assembled efficiently. I would recommend to anyone needing office furniture.
