Realspace PRO™ Quantum Recycled Mesh Mid-Back Task Chair, 40 1/2"H x 30 3/10"W x 26 1/5"D, Black

Pros: Appearance/Design, comfortable, features, functional, Quality of Material, Size & Weight, Well Made/ Sturdy, easy to assemble

I purchased this chair for my home office because a "conventional" adjustable padded mid-back chair was causing me to suffer lower back and tailbone pain. This mesh chair has no padding to press on sensitive spots, but because the mesh "gives" it is extremely comfortable but still very supportive. An added bonus is that the mesh affords excellent ventilation. I loved this chair so much I bought a second one for my office two weeks later. The chair is very easy to assemble (clear, simple instructions) and includes the one tool needed), and you can even leave off the arms if you prefer armless. Chair is fully adjustable and works well for all size people. The packaging was excellent as well.

Pros: Appearance/Design, comfortable
Cons: Easily Damaged

The latch that stops the seat from sliding forward/backward is snapped off after 1 hr of use. I'm only 150lb.

After examining the latch, I found out that the housing that holds the latch is cracked and the latch completely came off. This is definitely a design flaw. The housing of this latch should be made of steel instead of hard plastics. For this kind of price, all the pieces should be designed with durability in mind. This is not supposed to be a disposable chair.

1-star is the lowest I can select. 0-star is more like it.

Pros: Appearance/Design, comfortable, features, functional, Size & Weight
Cons: Easily Damaged, Quality: Flimsy, Wobbles, bolts are not of good quality, design of backrest poor

My boss got me this chair in August of 2008. The mesh design helps keep me cool & the seat is very comfy. I like all the adjustments & positions available. However the height adjustment of the back rest always falls out of place & I'm constantly having to reset it.

After reading the reviews about the faulty bolts for the back rest, I just made sure to check the bolts tightness on a bi-weekly basis, even though the instructions suggest to check every 3 months. I did discover that they were coming loose on a regular basis. Well around January '09 I came in to work one day and noticed a bolt head on the floor below my chair, one of the bolts had sheared off and half of it was stuck in the chair!
So I changed my bi-weekly bolt check to a weekly one & hoped that it would hold up. Well this morning the other bolt broke (same as the last one) and the part of the backrest that attaches to the seat (which is plastic) broke & the whole thing fell off, nearly taking me with it.

I called the warranty place & they need proof of purchase before sending me a replacement back rest & bolts, but I still have to buy a bolt extractor to get the two sheared off bolts out.

I'm well under the weight limit & don't understand why these bolts come loose so often. I wouldn't suggest this chair for purchase. At $300+ you should be able to expect more than 9 months of use. At least it's covered under a 5 year warranty, but being in my old chair until the replacements comes doesn't sit well with me.

Pros: Appearance/Design, comfortable, Quality of Material, Well Made/ Sturdy
Cons: the arm rests move quite a bit

I find this chair to be extremely comfortable. One con I found is that the arm rests tend to move quite a bit and I am always finding myself repositioning them. I would recommend this chair to anyone even considering the arm rests and the price being a little steep

Pros: Appearance/Design, comfortable, features, functional, Quality of Material, Size & Weight, Well Made/ Sturdy, adjustable arms
Cons: mesh seat gets uncomfortable if wearing shorts, seat can get uncomfortable

This chair is great. I work from home doing tech support for up to 12 hours a day and this chair is well worth the price. The armrests are lightly padded and swivel side to side as well as adjust up and down. I do wish that the back of the chair pushed forward a bit more as I like A LOT of lumbar support (like you get with a typing chair), but I just added my own lumbar support pillow and it works fine. The mesh seat is mostly comfy, but you do need to adjust your position every 15 minutes or so to stay comfy. Also you have to wear pants due to the mesh; shorts are very uncomfortable on the mesh as it will pinch into your skin. The mesh does keep you staying cool though. Overall I am happy with my choice and would recommend this chair.

Pros: Appearance/Design, comfortable, features, functional, Quality of Material, Size & Weight, Well Made/ Sturdy
Cons: sits too low but easily fixed

I LOVE this chair. The comfort is wonderful, and all the adjustments make it easy to sit for hours. To me, this chair is actually more comfortable than the Aeron chair I use at one of my clients.

The ONLY issue I had with this chair is the height. I'm 6', but most of that's in my legs. The chair just sat too low. I was reaching up to my keyboard and mouse.

So, I came up with a super easy fix. Flip the chair on its back, then take a hammer and smack the center post sticking out of the bottom, using a piece of wood to not mess up the post. This will loosen the base so you can remove it. Then, take clear packing tape and tape the first four inches of the bottom of the center post with about 20 layers or so. Put the bottom back on and voila! The chair now sits about 2" higher and is still very stable! The tape does not show at all and has lasted months this way.

Now it's perfect!

Pros: Appearance/Design, comfortable, functional, Quality of Material, Size & Weight

mesh makes it breathable and cool. All parts seat, height, arms, back, seat back/forth are adjustable making it very convenient for people that spend most of their time sitting at the office.
Highly recommended!!!

Pros: Appearance/Design, comfortable, features, functional, Quality of Material, Well Made/ Sturdy

I sit in a Herman Miller Mira chair at work and needed something similar for my home office. This Quantum chair is very adjustable (even more than the Mira). The only complaint I have is the arm rest height didn't go down far enough (it was about 1.5-inches too high) and would cause my shoulders to get sore. I solved the issue by taking a Dremel to various parts of the arm assembly and cut it down to the height I needed.

Pros: Appearance/Design, comfortable, features, functional, Quality of Material, Size & Weight, many ergonomic adjustments

I have an arm injury due to poor office ergonomics, and therefore had to buy a new desk and chair. I sat in chairs at stores, and this was the only one I thought felt comfortable immediately. In researching what I needed in a chair, there are a number of adjustments recommended by OSHA, including arms that adjust for both height and width. I looked at some of the more expensive ergonomic chairs, such as the Herman Miller Equa and Caper, and realized they didn't have anywhere near the adjustments this chair does! (I think the more expensive Aeron chair does.) This chair has many of the features of $700+ chairs at a fraction of price. It includes the arm height/width adjustments, as well as the seat depth adjustment. All are important if you need to sit properly and painlessly. I am so grateful to the many people who positively reviewed this chair, which helped me reach the decision that this was the chair for me. Great buy. My one con is ease of assembly. It was hard to get the wheels pushed in. If you have weak arm strength, you'd need help. (I did.)
