First impressions

Humanscale is on a mission to simplify the products that you interact with while you’re working. This design ethos is clear to see in the world chair as its minimalist appearance and simple lines look fantastic while remaining unobtrusive, so that it won’t take over the room that you have it in.

On the Humanscale website you’ll find a mind-boggling array of mesh styles and colour combinations that will suit a whole range of interior decors. There are three frame colour options (black, grey and white) and the seat can either be made with a textile overlay to the mesh or can be constructed so that the mesh can clearly be seen on the backrest and the seat. This was the option that we thought looked the best and made the chair even easier to blend in with a whole host of different surroundings.

How it works

The brand’s dedication to simplification is also to be seen in the chair’s operation, as it has just eight major parts and three manual settings for height and depth.

Everything else adapts automatically depending on how you sit and move in the chair, from its weight sensitive reclining mechanism to the flexible but strong non-stretch mesh. Diffrient collaborated with textile designer Elizabeth Whelan on the mesh to provide a backrest that would mould to the shape of the user’s spine and provide constant, moveable lumbar support.

This means that the chair doesn’t have to be manually adjusted every time someone different sits in it. Instead, it automatically adapts to the physicality of whoever is using it, which means it can work equally well in a home with multiple family members as it would in an office environment.

How it feels

The first thing you’ll notice when you sit in this chair is the non-stretch mesh that both the seat and the backrest are made from. It offers ultimate comfort and excellent air circulation while at the same time feeling totally supportive. It provided instant lumbar support without the need for lots of manual adjustments.

We also loved the fact that we didn’t have to constantly fiddle around with knobs and levers every time we wanted to sit back – instead, this was all controlled by the weight-sensitive, counterbalanced recline which automatically adapted to the position our body wanted to be in and provided solid ergonomic support.

We also found that this unique counterbalance mechanism allowed us to maintain a constant eye-level with any screen or monitor that we were working on.

Cleverly, the armrests connect to the backrest rather than the seat so they stay with the body as you recline. The seat itself is also totally frameless so there’s no extra pressure being put on the backs of the legs when you have to sit for a while.

The mesh also cuts down the weight of the chair, and at only 14kg the chair is light and moves around freely on the standard casters that roll well on both hard floors or carpet.

The only manual adjustments are to be found at the seat pan, which can slide forwards or backwards, so that you can allow for the recommended 2-4ins of clearance between the front of the seat and the back of your knees. And while you can manually adjust the height of the seat itself and the armrests be warned, the world doesn’t swivel, so if this particular kind of movement is important for your work it could have some bearing on your purchasing decision.

The verdict: Humanscale Diffrient world chair

Reinventing the way we sit is a pretty tall order, but the Humanscale Diffrient world chair has produced a seat that’s brimming with effortless ergonomic comfort all contained in a sleek design that adds a touch of modernity to a workspace.

It really felt like the chair was protecting us from some of the more insidious side effects of sitting down, and the generous 15-year warranty means that Humanscale really believes in the product that it has come up with.
