Refunds & Returns

If you need to exchange your product, you may do so.  You, as the customer, are responsible for any shipping costs throughout any returns or exchange processes. 

Not all orders are available for return once they have shipped.  We order products directly from the manufacturer. Therefore, if the manufacturer will not permit us to return a product, we cannot offer you a return. This often varies on a case-by-case basis; please reach out to us if you would like specific information on your brand and/or product.

Seller reserves the right to refuse to refund any deposit or payment, or cancel any payment due, and any owing until such time as Seller a) is in receipt of the goods b) has inspected the goods and c) in the Sellers discretion, has found the goods to be free of damage. All refunds will be provided within 5 business days once the product has been returned to the warehouse and inspected for damage.

Shipping Times

We promise to do our best to get your order to you as soon as possible.  We provide estimated shipping times on the product pages based upon what our suppliers and freight companies tell us, and those estimated shipping times may change or vary without notice (Due to supply chain issues, the steel mills behind on making metal, the manufacturers delayed because of the mills, the overwhelming demand on shipping, factory/warehouse and dock workers and so on).

A chair that does the job
Color: Black, Color: Black
I’m really happy with this chair overall. I wanted something comfortable, sturdy, breathable, and spacious enough for long hours at my desk when I work from home, and this chair delivered. I’d easily give this chair five stars because it exceeded my expectations in comfort, quality, and overall value. Comfort and Support The mesh back keeps it cool and comfortable during extended use. One of my favorite features is the adjustable lumbar support. You can manually position it exactly where your lower back needs support, and it fits the curve of my back perfectly. It provides great support without feeling too firm or uncomfortable. Build Quality and Design The chair itself feels solid and well-built. It doesn’t creak or make noise when shifting around, which makes it feel stable and high-quality. The seat is roomy and comfortable, and the overall design looks clean and modern. Easy Assembly It also came with an instruction manual that was extremely simple to follow, and assembly was very easy. I was able to put the chair together by myself in about 20 minutes without any help. Armrest Functionality I also like the armrests. They aren’t adjustable by height, but they do flip all the way up, which is surprisingly convenient. You can easily slide the chair under a desk or use it as an armless chair when needed. Packaging and Presentation Another thing worth mentioning is the packaging. Everything arrived extremely well-packed. Every individual part of the chair was wrapped securely, including bubble wrap protection for the components. The hardware and accessories were neatly organized, and the chair even came with the necessary tools for assembly in case you don’t own a drill or tool set. The presentation and packaging were excellent and showed real attention to detail. Overall Impression Overall, this is a fantastic office chair for the price: comfortable, supportive, sturdy, easy to assemble, and packaged exceptionally well. I’d absolutely recommend it and would confidently give it a five-star rating.

Nice chair
Easy to assemble and looks clean in my home office. The lumbar support is actually helpful, and I like that the arms flip up so I can tuck it under my desk. It’s comfortable for a full workday, though the seat could be a bit softer. Overall, solid value for the price.

Comfortable and easy to move around
This chair is really comfortable. The seat cushion is soft but supportive, and the mesh back keeps my back cool during long workdays. The lumbar support helps a lot with my posture. What I especially like is how smoothly the casters roll — glides effortlessly on my floor, no noise at all. Assembly was quick, around 10 minutes. The flip-up armrests also help save space when pushing the chair under my desk. Great value for the price. Highly recommend for anyone needing a solid, comfortable home office chair.

Great chair at a good price
It's a great chair, comfortable and reasonably priced for an ergonomic office chair. I usually don't write reviews, but I also understand how purchasing an office chair can feel overwhelming with so many choices. I needed to replace the chair I'd purchased in 2020. At the time I'd not spent a lot of money, not sure if working remotely would be temporary or permanent. It lasted about as long as one might expect. I did quite a bit of research choosing a replacement. I'm always hesitant to purchase furniture without trying it out in person. This chair is worth the price, not on the higher end of what's available but definitely not cheap. I've had it for about three weeks and so far, it's perfect for the 8-10 hours I spend in it during the week. It arrived early, a great bonus. Assembly was quick, with easy-to-follow directions and all the tools and parts needed. (including some spare screws). I agree with others who mentioned that a spare set of hands would have helped, but I had no issue doing it myself. It's a sturdy chair with good lumbar support. The adjustability of that feature can accommodate different heights. (I'm around 5'4") Changing seat height or whether the back tilts or remains stationary are all easy to accomplish. The one minor caveat is the seat is leather, so in warm weather and shorts season, it's not ideal. I solved that by purchasing a cover (because of the way the chair fits together, I purchased one that covers both the seat and back because a seat cover by itself would not work). That has worked fine and I'm not sure whether I'll keep the cover on all year. Overall, it's a great chair at a good price.
