    If you sit in this chair you will want to take one home! Very styled and all mesh. Great chair for shorter needs to regular needs with one of the widest range of heights and seat depth.

atWork For You!

Purchased lockers on behalf of my workplace through Lover's atWork, and am super pleased with the entire process. They are very knowledgeable, patient while requesting quotes, and easy to get into contact with. They are honest with lead times, and our goods arrived even quicker than expected.
Definitely recommend for all of your furniture needs, it was overall a very seamless purchasing experience!
Top tier customer treatment and service
Luke Howkins, Operations Manager at AtWork, delivered.

He took the time to understand our office needs and provided clear, effective solutions for our new layout. No guesswork—just solid advice and execution.

Professional, efficient, and results-driven. Would work with him again without hesitation.

I purchased my Humanscale Ergonomic Under Desk Foot Rest - HUM Natural Wood from atWork Office Furniture and am so very pleased with the quality of the product and the exceptionally fast and courteous service I received.

My Under Desk Foot Rest has made the long hours I spend at my Computer and Desk so much more bearable, relieving back pain as well as aching in my legs and feet. I especially love the ability to rock the foot rest and adjustable Foot Rest height.

I highly recommend this Desk Foot Rest and especially the great service provided by atWork Office Furniture.

Thank you for a great shopping experience
Awesome team and great prices. Easy ordering process from a large selection and the delivery team was fantastic. Aaron is the man and hooked us up with everything we needed.
New furniture looks great and service was excellent!
Incredibly helpful and accommodating. Large selection of desks and chairs, with beautiful options for customization. They kept me aware of the shipping and delivery process and put everything in place upon arrival, setup ready to use. If I need further furnishing for my new career, I know where I'll be going.

Lovers atwork will take great care of you! James treated me great right when I walked in the door. He shared solutions to my needs and I found a great product. It is definately the place to go if you need chairs, tables, desks or office furniture. Aiden and Dennis took great care to load me up. Great service all around!
We were given extremely helpful advice on choosing the right table and chairs for a newly renovated space in our home. Thank you to Mark Small for all the help. We are so pleased with the quality and comfort of our purchases. The furniture design and colours blended perfectly within the space. Delivery and setup went flawlessly as well. We would highly recommend Lovers At Work in London.

We have bought refurbished computer chairs and a couch here in the past and they have been great quality. We just went in trying out new computer chairs and Mark was very helpful, knowledgeable and understood what we were looking for.
Lovers atWork were fantastic to work with. They handled our new office furniture and coordinated a smooth move over the Christmas break, including relocating our existing furniture and setting up the new space. The team was professional, organized, and respectful. Big thanks to Andrew for leading the project so well, much appreciated!
Excellent products and service, the reason why I keep coming back. Canadian company

Update 2026:
Still using Lovers AtWork for all of our office furniture needs. Service is better than ever. You absolutely cannot beat their service or pricing.

Original: I can't recommend Lovers AtWork enough. I moved to a new office in July, and the process of ordering exactly what I needed could not have been easier. Their delivery people were superb, as were the warehouse staff who assisted me in adding to/changing my order at the last minute. When the furniture was delivered, the staff who came to my office were fast, courteous, did an excellent job assembling and positioning the furniture in line with my requests, and there wasn't a scratch on a single piece they brought in for me. They also offered to take all the trash/wrappings away at the end. I will be using AtWork for all future office furniture needs, and I wouldn't hesitate to rec\commend them to any of my colleagues or fellow business owners.
Love my wheeled chair! Easy to put together.
Rob, Bryan, and Eric Williams are all extremely knowledgeable and took the time to ensure everything was completed seamlessly from start to finish, from the initial purchase through to the warranty replacement.

They genuinely care about their customers and clearly take pride in the quality of their work. I truly appreciate the attention to detail and the overall positive experience. Highly recommend!
Helpful support, prompt service and fair pricing!
Great service, bought from them 2 times with James ! Good and legit company !
I have been dealing with Lovers for over 30 years. They have fantastic customer service and sales people. Their delivery people are awesome and great to deal with.
James was super helpful in guiding us to find new office chairs. Would absolutely recommend!
