A few recent product reviews.
Two distinct pieces that look coordinated. The green-and-gray seat cushion and four-lobed lumbar piece share the same palette without pretending to be one connected unit. I can position each separately.
Alana K.
Four-lobed back cushion is distinctive. The lumbar piece has two upper and two lower rounded zones around a sculpted center. It looks far more intentional than a simple rectangular pillow.
Jorrit P.
Useful freedom to separate the set. I keep the seat piece at my desk and sometimes move the lumbar cushion to a reading chair. The two-piece format makes that possible without disturbing both.

A closer look, feature by feature
Seat + lumbar set
Two distinct contours for one existing chair
SitContour Duo combines a raised-edge seat cushion with a separate four-lobed lumbar form. The selector switches between the verified green-and-grey and black-and-grey cover distributions.
Two-piece set2 verified coloursSlow-rebound foamFixed contours
Seat geometry
Raised outer contours around a shallow center basin
The seat cushion's fixed profile includes a lower center area and an elongated opening. No contour height, product dimension, or user-fit range is supplied, so fit should be checked on the intended chair.
Two waist-and-seat colour optionsRaised seat perimeter
Separate lumbar form
Four rounded lobes frame a sculpted center
The upright lumbar cushion has a shallow top dip, rounded side lobes, and a central channel. It is a separate piece rather than a permanently connected chair system.
One seat cushion plus one lumbar cushionShallow seat basin
Slow-rebound core
A responsive feel without a claimed firmness grade
The source identifies slow-rebound memory foam in the set. Foam feel can vary with temperature and use, and product documentation does not include density, firmness, or rebound timing.
Slow-rebound memory foamElongated center opening
Chair-top use
A movable two-piece layer for seated work
Place the seat cushion fully on a stable chair and position the lumbar piece against the backrest. Because no compatibility range is published, check for overhang, shifting, and blocked chair controls before sitting.
Visible construction
Sculpted foam shapes with clearly stated unknowns
Both exact colour sets and their slow-rebound memory-foam description are source-backed. Product dimensions, exterior textile composition, care method, and load rating are not documented and are not inferred from packaging measurements.
Slow-rebound memory foam
Product documentation identifies the foam type but provides no density, firmness grade, or rebound test.
Two fixed sculpted profiles
The seat basin and lumbar channel are built into separate pieces with no adjustment mechanism.
Package data kept separate
35 × 17 × 39.5 cm and 1.12 kg appear on packaging artwork; they are not stated as cushion dimensions.

Honest Fit Check
This cushion isn't right for everyone
We'd rather you buy the right thing than the most expensive thing. A few cases where this might not be your best match:
It changes your sitting height
Any cushion changes the relationship between your hips, knees, armrests, and desk. After placing it, check that your feet are supported and your forearms still rest comfortably.
It's a seat, not a backrest
The cushion improves how you sit, not how your back is supported. It isn't a substitute for a chair with a supportive backrest.
Still not sure? With 60-day money-back guarantee — we pay return shipping, there's no risk in trying it at your own desk — if it doesn't fit your setup, send it back.

Seat basin is broad and shallow
The raised perimeter surrounds a gentler center rather than a deep bucket. The elongated opening is clearly visible and runs along the middle-rear area.

Slow-rebound feel matches the description
Both pieces recover gradually after pressure rather than snapping back immediately. I am not assigning a firmness grade because none is published.

More fit information would help
The set is accurately shown, but neither cushion has confirmed dimensions or a universal chair range. My compact chair felt crowded when I used both together.

Green and gray feels less corporate
The muted green upper areas soften the look of my black chair, while cool-gray sides keep the pair coordinated with the desk setup.

Complete set arrived in one shipment
Tracking showed a realistic delivery range, and both the seat and lumbar pieces were present when the parcel arrived. The colors matched across the set.

Black lower piping sharpens the seat edge
The dark piping beneath the gray sidewall gives the seat cushion a finished outline. It is a small visual detail that the gallery captured well.

Owen F.🇬🇧
Fair value for a matched pair
At this price I received two differently shaped memory-foam pieces rather than one generic pad. The separate functions and coordinated finish justify the bundle for me.
