To sum up, I recommend this product to children on a small budget or squeaky fetishists, because at the slightest shift in your seat, this monster growls restlessly! ps. At the first loss of the wheel, I turned to the amazon|aliexpress where I bought it, they sent me to all 4 sides, they say it’s not a guaranteed case) With its pros: It's a little nice to sit, not bad leather deputy, bought at a discount for 9700 (+1000 bonuses) Its cons: Having a height of 188, it is uncomfortable to sit, this is a chair for children. The armrests are not comfortable, on the front "cushion" the foam has deteriorated so that a plastic plug sticks into the leg. Disgusting wheels, after 3 months one flew off (I bought a replacement), by the way, the bayonet of the wheels is non-standard and you will not find ideal replacements, after another 3 months the second wheel flew off (printed on a printer, sits like a glove, but few people want to pay for a 3D printer ). And the biggest drawback is the creak, it always and everywhere follows the happy owners of this product, it arose after about a month and a half of active use of a 70 kilogram person, you can’t get rid of it, because the base of the seat is wooden, and bolts from the kazlift are attached to it (which the word is also not fantasy). I tried to lubricate it with latex, and wd-40, and machine lubricant, and some other lubricant, how it creaked and creaked!
