Love it!

Because of my job, I have to sit on the chair for long periods of time. One of my top priorities was finding a chair that supported my lower back while being in a comfortable position for gaming. This chair does it. it was super fast shipping and i am very pleased with this chair. Price is right, comfort and quality is good. I sit perfectly at my desk for typing and gaming. It’s so comfy and was easy to assemble. I can sit in this chair for hours playing game without it hurting my back. 10/10 would recommend this chair!!

Fantastic chair

Must buy

I've used this every day for the past several months for work and I love it. I got it out of the box and assembled it in 25 minutes. (Mind you I stop during assembly to talk to my wife for 5 minutes). It's comfy and sturdy. The support pillows are nice and can be moved around depending on where you need them.
Also my kids tried it and my daughter said "is this a sleeping chair" So that should tell you how comfortable this thing is. Very happy with this purchase.

Great chair

I work from home and needed a chair that would provide comfort and support. I find myself in back to back meetings and most days have to stay in the chair almost all 8 hours.
Everything inside was very nicely packaged. Everything that could possibly dent or scratch was wrapped in foam. Everything else was sealed nicely in plastic. The bolts and screws were clearly labeled.
After using the chair for about a month now, I can say that I really love it. The size of the backrest is perfect for me, and the various adjustable functions - such as the arms, seat height, and backrest height - work incredibly well. It's so easy to find a comfortable position without having to stretch or strain too much.
Overall, I've found this chair to be incredibly comfortable and supportive, which is exactly what I was looking for. It's been a great addition to my home office, and I'm really happy with my purchase.

Fantastic Chair!

Purchased after my old chair finally gave up. I debated this chair over other brands and a number of options on numerous other websites and I must admit, I was reluctant for the price which was one thing that put me off some of the rival brands. I have 2 friends with Secret Lab chairs and I had been tempted wheb they'd had offers on but I wasn't paying silly money if I could help it and in my searches this was the one chair that really stood out to me. I eventually overcame my reluctance to spend more than a couple of hundred pounds having toiled over it for a good couple of days and I have to say, I have no regrets whatsoever and I'm actually really happy with my purchase! The chair arrived via DPD within 2 days and was so easy to assemble, didn't even really need any of my own tools either as the Allen key was included! Took me all of about 10 - 15 mins to assemble alone between work and in all honesty, this is definitely as good as my friends chairs if not better and absolutely a whole lot healthier on the wallet!
The parts seem very sturdy and we'll built, the stitching and materials appear good quality and I will honestly never go back to a basic office chair ever again! Work is finally going to be a pleasure again from a sitting at the computer perspective at least! Lots of adjustable fittings, moves about very smoothly and quietly, looks and feels great and was nice to get a chair in the colours I wanted without over ridiculous branding!
Would definitely recommend these chairs to anyone!
