Upside innovations was a pleasure.

Upside Innovations was a pleasure to work with from design to delivery. Nick Bishop was responsive and quick to get a quote started, and Tish Carroll did an excellent job shepherding the job through the engineering design, fabrication, and shipping stages, expediting the process when the deadlines got tighter on my end. The product arrived early and was a pleasure to install – all of the hardware clearly marked and bagged, and the pallet strapped and wrapped securely. These stairs are being used for robotics research/testing and are working flawlessly. I would recommend Upside to anyone looking for professional crossover stairs for their project or building.

Thank you for the quality work.

Thank you for the quality work. The stairs definitely enhance the look at Lakeside [Garden Apartments]. We appreciate your service to us, and we look forward to working with you again in the future.

The stairs worked out great.

The stairs worked out great, and they love them!

Paul R.

I am very impressed.

It went together well, I am very impressed that your fit and finish was as tight as it is. Thanks again to everyone involved in the project.

Vince B.

Couldn’t be happier with the whole experience.

The quality was fantastic, and they showed up quickly. From the time they were pulled off the delivery truck, the stairs were assembled, stood up, and lag bolted into the floor in under 1 hour. We really couldn’t be happier with the whole experience we have had with Upside Innovations. Plus, the stairs are much sturdier than I had even hoped for. Below is a picture of the steps installed on the side of our gun range. Thanks again for the great job.

So easy to work with!

Upside was so easy to work with! From estimating, to product selection, and all the way to delivery, they were very responsive and easy to work with. When we need another set of stairs, we will be buying them from Upside Innovations.

The steps are well built.

The steps are well built and sturdy enough to handle our needs safely but yet light enough for two men to move without the use of equipment.
