Kaiser 4 V2 XL is the latest generation of the large premium chair from AndaSeat. The model is aimed at users looking for space, a wide range of adjustments, and durable materials. In the XL version, the manufacturer specifies a recommended height up to 210 cm and weight up to 180 kg, as well as improved integrated lumbar support with the ability to lock at various angles, a magnetic neck pillow, and new armrests. This is not just "another large chair" — it is a carefully designed platform for long computer sessions, from gaming to daily work.

Design and Materials
On the outside, the Kaiser 4 V2 XL looks impressive and convincing. Classic racing-style proportions, with a wide seat and high backrest, are combined with clear seam geometry and large armrests. The main structure features a steel frame and metal adjustment mechanisms that feel like a single solid piece when assembled. The upholstery is available in two options: synthetic leather ArteDiPelle or natural linen EverSoft; both are designed to be wear-resistant, easy to clean, and come in a variety of colors — from classic black to bright "Cyber Green" and "Zen Purple".
The fabric version EverSoft has a pleasant tactile feel and better ventilation in the summer, while the synthetic leather is easier to maintain. For our conditions, the fabric is a successful compromise: it doesn't feel cold in winter, "breathes" in summer, and maintains its original appearance over time. This is distinctly felt during daily use, where the microclimate of the seat takes precedence over just the aesthetic appearance.
Assembly and First Impressions
The chair comes disassembled. Included are basic tools and clear instructions. Assembly poses no difficulties and takes about half an hour. During the initial acquaintance with the chair's features, the large wheels with a diameter of over 70 mm attract attention: they roll quietly, without rumbling, and leave no marks on laminate or parquet floors.
Size and Fit
XL is not just a marketing gimmick. The backrest is tall, the shoulder area is wide, and the seat cushion is deep, with enough room for "above average" height and hefty individuals. The author, with average parameters, also felt comfortable: there is no pressure at the "wings," knees do not hang in the air, and body position is not dictated by the shape, as is often the case with tighter models. Such spaciousness is useful for those who work 8–10 hours: positions inevitably change throughout the day, and additional centimeters do not lead to discomfort.
The official sizing matrix confirms: XL is designed for heights approximately 181–210 cm and weights 80–180 kg. If you are below 175 cm and weigh less than 80 kg, it is advisable to pay attention to size L, although there may be cases for "growing into" — the main thing is that the back and neck are in support zones.
Filling and Firmness
The seat and backrest are made of medium-firm foam filling. The foam evenly distributes pressure and quickly regains shape after prolonged pressure. This offers a feeling of "controlled softness": you do not sink in, but are also not sitting "on a board." For long gaming sessions, this is probably the most balanced option.
Integrated Lumbar Support
A distinctive feature of the Kaiser 4 is the new lumbar support system. It extends up to 24° and locks at any angle thanks to an elastic mechanism — essentially, this is a "pop-up" block that changes the geometry of the backrest, rather than just a pillow that moves up and down. Besides angle, height and depth are adjustable, so customizing the curve for a specific back will be straightforward. The manufacturer emphasizes the 4-level/4-direction adjustment scheme, and this is noticeable: transitioning from a vertical position to a "semi-relaxed" position won't require re-adjusting the support.
Competitors often showcase either pulleys with straps or simple "wheels" for height adjustment. Here, the solution is costlier but works noticeably better: the back does not lose support when changing the angle of the backrest or tilt of the seat; the support point remains where needed.
Next-Generation Armrests
Another improved detail is the armrests. In the manufacturer's terminology, this model utilizes 6D armrests. This means an expanded range of adjustments: moving forward-backward, up-down, left-right, rotating in the horizontal plane, and adjusting the tilt of the upper pad. This allows for maximum comfortable adaptation of the armrests for the keyboard/mouse as well as for a game controller or smartphone. The pads are soft, with a rubber-like coating.
Recline and Rocking
The backrest adjusts over a wide range; the specified 90–135° covers both the working mode and short breaks to "rest." The seat can be switched from a fixed position to rocking mode, and the spring stiffness is adjustable using a regulator under the seat. In everyday use, what matters more is not so much "how many degrees" but the stability when changing the center of gravity — here, the mechanics work reliably, without jolting.
Neck Pillow
The neck pillow has a magnetic attachment. It seems like a minor detail, but after this, one doesn't want to return to the usual strap attachments. Thanks to the magnet, the pillow has a wide range of height adjustment, so it easily adapts to both low and high seating positions. Inside, it uses memory foam and a cooling layer.
Gas Lift and Base
The lift system is class 4, which is a modern "gold standard" for chairs of this class. Stability is provided by a massive star base and large rollers. All this combines to give a sense of reliability — the model is designed for years of operation without the need for service maintenance.
Everyday Experience
In use, the Kaiser 4 V2 XL does not impose a single "correct" posture. Thanks to the combination of a deep seat, adjustable backrest, flexible lumbar block, and adaptive armrests, the model allows frequent position changes without losing comfort. After 3–4 hours of continuous use, there is no usual feeling of fatigue in the lower back, and shoulders do not get stiff due to poor geometry of the armrests, as is the case with less successful models. This is a case where the set of adjustments works as a system, rather than just a list of "check marks" in the specifications.
The fabric proves to be reliable: cool in summer, not cold in winter, dust is easily removed with a vacuum cleaner attachment, and individual stains from drinks do not have time to set if responded to in a timely manner. The synthetic leather looks more formal, but for maximum comfort, we recommend EverSoft.
Who This Chair Is For
First and foremost — for tall users and those who spend many hours at a computer. If you are not looking for the lowest price but seek "no compromise" comfort, the capabilities of the Kaiser 4 V2 XL truly cover most scenarios — from productive work with a keyboard to gaming on a gamepad or console. At the same time, it is important to precisely fit the size: XL is a "large" chair; individuals shorter than 175-178 cm may find more comfort in the L version.
Overall Impressions
The AndaSeat Kaiser 4 V2 XL is a modern flagship for those who want everything in a chair and are not willing to compromise. Smart ergonomics, reliable mechanics, a wide range of adjustments, and various upholstery materials make it a versatile solution for long working and gaming sessions. The recommended sizing matrix for height/weight honestly targets "big" users; everyone else should consider the L version.
Thus, if your budget allows, the Kaiser 4 V2 XL appears as a rare example where the package truly includes "everything you need," and everything works as a cohesive whole.
