Two Options

The new S5 chair is released! Experience a new dimension of comfort with larger headrests, higher gas cylinders, and retractable footrests. You can enjoy every minute of your work by using this office chair.

Combining Comfort with Functionality

Work comfortably with the S5 Chair, an adjustable work chair that is highly functional. K+r shrink meshes back and cushioned seat ensures lasting comfort, with a simple aesthetic that blends with most office styles.

Dynamic Variable Lumbar Support

The lumbar support can be adjusted independently to ensure a customized fit. By providing external support to the lower back, it helps the spine maintain its natural curve while sitting, as well as reducing pressure on the vertebrae.

Responsive Tilt System

Functional tilt mechanism allowing angle adjustments in four positions. Backrest tension can be adjusted up to four levels based on body weight for improved responsiveness and flexibility.

High-density Cushioned Seat

The S5 seat is made of high-density foam and covered in high-quality fabric. The seat depth can be adjusted to accommodate your legs as needed for all-day comfort.

Three-way Adjustable Armrests

The armrests can be adjusted in all three dimensions, allowing you to adjust them by height, forward/backward, and sideways angle. A padded surface is also provided on the top of the armrests to offer you comfort and support.

Lengthened Headrest

The longer headrest provides you with better head support, preventing you from hunching forward, scrunching your shoulders, and stressing your back. An ergonomic headrest makes leaning back and taking a short nap easy.

Retractable Leg Rest

Using an extended footrest to rest your legs and enjoy optimal comfort. By supporting the lower limbs with the footrest, you are able to find the ideal position for taking a nap or break.

Mute Casters

Nylon mute wheels roll smoothly on any surface, without damaging wooden floors or your beautiful rug. The non-slip and sturdy caster base helps reduce lower limb pressure and is durable.

Sturdy and Professional

S5 chair features a sturdy frame that is strong and durable as well as a mesh lumbar support that keeps you comfortable for hours on end. It also comes with an ergonomic design and multiple professional adjustments to ensure the best balance of ergonomics and comfort.

Austin S (Midvale, US)
Great comfort but sits super low

Just received this chair for Christmas and it's a fantastic upgrade. I am a good height for it, since I've noticed that is the biggest complaint. The couple of items I have an issue with is the arm rest sit way forward so hard to rest them when I am in my desk. Most of all, it sits WAY to low. I have it extended fully and it raises maybe a foot. Not sure if my base is bad or the hydraulic is faulty but the hydraulic practically touches the floor and it won't raise any farther.

Picture below shows the chair fully extended not sure if that is a good comparison but NOT great.

Hello Austin,

Thank you for taking the time to write a review and leave your most authentic using experience. We will record the position deviation of the armrests that you have reflected, and may improve this problem in future S5 upgrade chairs. In addition, you mentioned that the gas rod is too low. Other customers have reported the same problem before, and the air rod of the S5 is indeed a bit lower than other models of chairs. If you feel uncomfortable to use, please let us know(reply this comment directly or send us an emai, and we will immediately reissue a longer air rod for you free of charge. After replacing it, the overall height of the chair will be increased. And don't worry, we will also attach a replacement installation guide to teach you how to replace it.

Hope the above information is helpful to you. Awaiting your response :)

This chair beats my office chair

I've been looking for a chair that's similar to my one from the office. And I've found a better one. This chair is awesome and fits well, comfortable out of the box and took about an hour to put together. 10/10 would recommend again.

This chair is awesome

I got this chair because I was having terrible back pain with my old one. Since I started using it, I no longer complain of back pain. It offers great back support and has a reclining option as well.
The customer service is amazing. They sent me the wrong color accidentally due to a manufacturer error regarding the labels, and they solved my issue fastly and efficiently. I am impressed.

Very happy with the product.

The chair was delivered before the estimated date of delivery; Bravo! The chair was packaged very well with many protective layers. Assembled the chair by following summary instructions and it is well built. Sturdy, adjustable in many ways (just as described in the product description). Very happy with the product.

Worth every penny!

I was nervous to spend so much on a chair (and TBH from a company I had never heard of). But I read reviews and decided to go for it. This chair is worth every penny. It's strudy and strong - I was surprised how heavy the base was. I love all of the adjustments as my staff (we share a mental health therapy office) are different heights and sizes. This chair first everyone, from tall and slim to petite and curvy. My therapists all mentioned they felt more attentive in sessions and energized when they finished the day. I would buy another chair when the time comes to furnish a 2nd office.

Very Happy I Waited

31/2 months waiting. That was the amount of time before I could order the chair due to it being out of stock. After ordering the chair it was another two weeks before the chair arrived in the warehouse for shipping. Add to that another week for delivery it makes a long time to get a chair. Was it worth the wait? ABSOLUTELY!! Putting the chair together took me about an hour. No problems following instructions provided. The chair moves quietly and easily over the wood floor compared to other chairs I have had. The arms are comfortable and adjust so that do not interfere with the keyboard draw on my desk. Seat is very comfortable along with the lumbar support. Had occasion to contact customer support during my process and they were very prompt answering questions during the initial wait before ordering and especially during the shipping delay. See too many reviews about bad customer support but not the case with EazeeChair.

I love all the features of the chair, just wish that I could raise it higher

The Chair You Need!

I really love this chair! The design is cool and it is very sturdy. I’m a bigger guy so it being sturdy was very important to me and so far it’s been great! I sit at my desk for hours and this chair has given me the support I needed to push longer.
