Big-and-plush comfort or breathable all-day support?

Build quality and design

Winner: EXCEBET.

The EXCEBET is the more substantial chair on paper, with a 180kg weight capacity and a big-and-tall design that immediately signals sturdiness. Its 14cm pocket spring seat is unusual in this category and should feel more like an upholstered office sofa than a standard desk chair. The PU leather finish also gives it a more executive look, which may suit a home office or formal workspace better. The SIHOO, by contrast, uses a breathable mesh back and a more conventional ergonomic frame. It is well-suited to everyday desk use, but it does not match the EXCEBET’s sheer heavy-duty positioning or plush seat construction.

Comfort and ergonomics

Winner: SIHOO.

For long working days, the SIHOO’s adjustable lumbar support and 3D armrests make it the more adaptable ergonomic chair. Mesh backs tend to encourage a cooler, less sticky sitting experience, which matters if you work 8 to 10 hours a day. The 3D armrests should help more with shoulder and wrist positioning than fixed or basic arms, and the adjustable lumbar support gives you a better chance of matching the chair to your spine. The EXCEBET’s lumbar support and pocket spring seat may feel softer and more luxurious at first, but “soft” is not always the same as “supportive” over a full day. If posture and long-session comfort are the priority, SIHOO wins.

Performance for long sessions

Winner: SIHOO.

Although neither chair has a motor, tilt mechanism specs, or sit-stand features to compare, the practical performance difference comes down to heat, pressure distribution, and adjustability. The SIHOO’s mesh construction is better for temperature control, especially in warmer UK homes or if your office gets stuffy. Its ergonomic design is more likely to support neutral posture across long sessions, while the EXCEBET’s thick cushioned seat may feel excellent for short bursts but can become less ideal if you prefer firmer support and more movement throughout the day. If you sit for extended periods and want a chair that helps you stay alert and aligned, SIHOO is the stronger performer.

Price and value for money

Winner: SIHOO.

At £169.94, the SIHOO is £119.06 cheaper than the EXCEBET, which is a significant saving. That price gap is large enough to matter even if the EXCEBET offers a more premium-feeling seat and higher weight capacity. In value terms, the SIHOO gives you the more advanced ergonomic package for less money: adjustable lumbar support, 3D armrests, breathable mesh, and a strong review count of 5,780. The EXCEBET’s 4.5/5 rating from 947 reviews is impressive, but you are paying a premium for big-and-tall comfort and the pocket spring seat. For most buyers, the SIHOO delivers better value per pound.

User experience and real-world fit

Winner: Tie, depending on body type and preference.

This is where the decision becomes personal. The EXCEBET is likely the better fit for larger users, anyone who wants a wider, more cushioned seat, or people who dislike the feel of mesh chairs. Its 180kg capacity is a major advantage if you need reassurance on durability and support. The SIHOO is the better everyday work chair for most people who want breathable support, better adjustability, and less heat build-up. If you’re working at a desk for 10 hours, the SIHOO is more likely to keep you comfortable in a functional, ergonomic way; if you want a chair that feels indulgent and solid, the EXCEBET is more appealing.

Overall summary

The SIHOO is the better all-round buy for most people because it offers stronger ergonomic adjustability, better breathability, and far better value at £169.94. The EXCEBET is the specialist choice for bigger users or anyone who prioritises a heavy-duty build, a higher 180kg weight limit, and a softer, more executive feel. If your main goal is long-term desk comfort with good posture support, choose SIHOO. If your main goal is maximum plush comfort and a chair that feels built for larger bodies, choose EXCEBET.
