When it comes to delivering a satisfactory customer experience, the staff and owner at Miramar Office Furniture OVER-delivers.
Even with a last-minute request that was far from simple, they created the possibility to complete our order in excellence and made the entire process enjoyable.
With their support, my team has been able to help restore and renovate a project for very close to our hearts with the San Diego Center for Children.
If you are looking for a reliable business, you're in the right place. Thank you, Miramar Office Furniture!

We recently got some furniture delivered and put together at our office in Miramar and the guys were so nice and polite. They were fairly quick, but I was most impressed by how helpful they were and made sure that my director of operations loved where they placed the furniture and how it looked before they left. They even offered to move it if he changed his mind. I feel like that hard to come by nowadays so thought I'd leave a comment.

The store specializes in office furniture, so if you're looking for office items this place is worth the time, more than the average furniture store. We found exactly what we wanted at this store for a good price. Very friendly staff overall, and Bodhi's mom was so helpful and accommodating.

I have furnished offices for 40 people with Miramar Office Furniture as my one-stop shopping place. They have the best prices, selection and service I have found. They are always my go-to when I need anything. Sally and Urban are great to work with.
