Sergio Bellin drew Team Strike in 2008. Sitland's 2026 range still lists it, which puts eighteen years between drawing and order. Read it as continuity: for whoever furnishes ergonomic chairs for Indian offices in stages, the chair ordered later can match the one ordered first.
The mechanics Sitland declares today: a synchronised movement with five lock positions and antishock, a backrest tension matched to the sitter's weight, a Comfort Air seat in cold-foamed polyurethane, a lumbar support that rises and lowers. In mesh the backrest is a polyamide frame on a die-cast aluminium support; upholstered, it takes the seat's foam. Sitland calls it a complicity between seat and back.
Four versions, read by overall height. Lowest is the upholstered Operative, lumbar as standard, no headrest. A step taller is the mesh-backed Manager, which ships without headrest and takes lumbar and sliding seat as extras. Tallest are the two Executives, mesh or upholstered: the headrest adds the height, the backrest is the same on every version; the mesh Executive is the one with the UNI EN 1335:2020 type B declaration. Sitland photographs them at island desks, within open-plan workstation layouts. La Mercanti puts the year on the table before the finish: for a facility team replacing chairs floor by floor, a design that has stayed in the maker's range this long is the first thing to know.

A frame in polyamide, the engineering plastic Sitland uses for the back of all four versions, carried on a die-cast aluminium support painted black, or polished as an option. On the mesh versions the polyamide frame keeps the mesh under tension; on the upholstered Executive and Operative the same frame is padded with the seat's own foam. For a buyer the pairing is the one to remember: frame and support are the same on every version, so mesh or padding is the only choice that changes the backrest line of the order, floor by floor.
Between 420 and 520 mm on the two Executives and on the upholstered Operative, by gas lift. The Manager runs between 410 and 510 mm, and between 415 and 515 mm once the optional sliding seat is fitted. The comparison that matters is the desk: the four versions run over the same band give or take ten millimetres, so a floor that mixes versions does not mix seat heights. Where desks of different heights share a floor, the seat height is one figure to record per desk, and the same band applies whichever version stands at it.
Because trapped air works as a spring. Sitland's Comfort Air System casts the seat in cold-foamed, shape-retaining polyurethane and leaves air chambers inside it; the air held there gives under weight and pushes back, so the seat supports without packing down. The second effect is the one Sitland books as environmental: with the chambers doing part of the work, less foam is needed for the same seat, so less material goes into each chair. The same system is used on two other Sitland models, Uni and Passe-partout.
At work desks in an open-plan office. The largest picture shows four Team Strike with blue mesh backs at white island desks arranged around a tree in a wooden planter, with two cylindrical poufs and a pale armchair at the edge of the frame; a second one puts two chairs in anthracite mesh at a desk in front of a monitor, under pendant lamps. Those are the rooms Sitland chooses to show it in: shared desks in daylight, with the mesh version in front. A buyer planning a floor can read the pictures as the maker's own setting for the chair, and nothing beyond what they show.
It does not kick back. Sitland pairs the five lock positions of the synchronised mechanism with antishock: when the lock is released, the backrest returns to the free position under control instead of snapping forward against the spine. The behaviour is declared with the mechanism, so it is the same on all four versions, whichever one a buyer puts at a desk. The tension of the movement is tuned to the body weight of the sitter, so once released the back follows the body rather than pushing it.
Version, backrest, covering, armrests, base and castors, headrest: the choices that make up a Team Strike on the order sheet, with the options Sitland lists for each, so nothing is left to be guessed later.
Team Strike comes in four versions, and the first word on the line is one of them: Executive with mesh back, Executive with upholstered back, Manager, or Operative with upholstered back. The two Executives bring sliding seat, lumbar support and headrest; the Operative brings the lumbar support; the Manager brings the bare mechanism and takes everything else as options.
On the two mesh versions the backrest needs a mesh code, RF, RP, RR or RY; RY is the one Sitland pairs with the two fabrics that give the chair its Italian fire class on request. On the two upholstered versions the back is padded with the same foam as the seat and takes the covering chosen for the seat, so no mesh code is written on the line.
The seat, and the back where upholstered, is covered from Sitland's categories, numbered 1 to 5 plus 9 and A: each number groups a set of Sitland collections, and category A puts real hide on the surfaces the body touches with a coated fabric on the rest. A customer's own fabric or hide is written as COM or COL in place of a category.
Armrests are an option shipped separately, in four types: 1D adjustable in height; 2D in height and width with a fixed soft-touch top; 4D adding a top that also slides in depth and pivots; 4D with a polished aluminium support and a soft polyurethane top. They come in two families, one for the fixed seat and one for the sliding seat, so the family must match the seat chosen first.
The base is five-star black nylon as standard, or a flat polished die-cast aluminium base as an option. Castors are self-braking as standard, with free-running ones for carpet and rubber-tread or hollow rubber ones for hard floors. Last, the headrest: already on the Executives, added as a separate upholstered, pivoting item on the Manager and the Operative.
