Seat and back in one piece · Memory foam core · Removable cover
One connected cushion for your seat and lower back
Most people sit in more than one place during the day: at a desk, in a car or at home. A seat pad cushions beneath you, while a back pillow adds a separate contact surface behind you. This cushion brings those two contact areas together in one L-shaped piece. Place the seat section on a suitable chair and rest the upright section against the chair back. It is designed to work as a single unit instead of two accessories, so it gives you seat cushioning and lower-back contact together, without needing a new chair. Comfort and fit vary by person and chair.


The problem
When a seat pad is only part of the setup
By mid-afternoon, you may find yourself shifting in your chair, sitting forward, then leaning back again. The same search for a comfortable position can follow you home: a favourite book, a long drive or an evening in an armchair.
A seat pad adds cushioning underneath you. A separate lumbar pillow adds padding behind your back. With two accessories, there are two pieces to position, and two pieces to carry when you move to another chair. For a simpler setup, it helps to think about the seat and lower back together.
How it works
A connected approach to everyday seating
Rather than combining separate accessories, the design joins the seat section and the lower-back section into one structure. The idea is simple: bring seat cushioning and lower-back contact together, so more of you is cushioned at once.
- Seat section: sits on your chair and cushions beneath you.
- Upright section: rests against the chair back behind your lower back.
- One piece: nothing to line up twice, and it moves with you between seats.


Key features
Five features designed around everyday sitting
- Integrated L-shape: the seat section and back section work together rather than as separate accessories.
- Contoured seat with a centre opening: the shaped sitting surface has a central opening toward the back.
- Padded lower-back section: rests against your existing chair back. It gives lower-back contact, not a full-height backrest, and it is a flexible cushion, not a rigid frame.
- High-density memory foam core: cushioning beneath and behind you. The feel varies with body weight, room temperature and the chair underneath.
- Breathable cover: the outer cover helps airflow, for a fresher feel through long sitting sessions.
Size
Check it against your chair
The cushion measures about 17.3 inches (44 cm) wide, 15.8 inches (40 cm) deep and 14.6 inches (37 cm) high at the back section.
Compare these sizes with your chair's usable seat width, depth and backrest, and leave enough room for the cushion to rest securely. It adds some sitting height and takes up some seat depth.

Where to use it
One product, three everyday settings

At your desk
Emails, calls and paperwork can keep you at your desk for long periods. Rest the back section against the chair back, sit into the contoured seat and adjust the chair height to suit your desk.
In the car
For commutes and longer trips, check how it fits your vehicle seat while parked. Only use it if your seat belt fits correctly, the controls stay within reach, your view is clear and safety equipment is not blocked.
At home
Reading, television and time with family all bring you back to a chair. Choose a stable seat with a supportive backrest, and allow for the extra sitting height and reduced seat depth.

How is it different?
One piece instead of a seat pad and a back pillow
Traditional cushions focus on the seat. Lumbar pillows focus on the back. Ergonomic chairs stay in one place. This cushion combines seat cushioning and lower-back contact in one portable piece that moves with you, whether you are working, driving, travelling or relaxing at home.
- Memory foam cushioning in one connected piece, instead of two accessories to position
- Contoured seat with a centre opening
- Attached lower-back section that rests against your chair back
- Carry the seat and back sections together

Questions people ask
Will it fit my chair?
Check the cushion's sizes against your chair's usable seat width, depth and backrest. It adds sitting height and takes up some seat depth. It will not suit every chair or body shape.
Can I use it in my car?
Check the fit in each seat separately. In a vehicle, position it while parked and use it only if the seat belt, controls, view and safety features stay unobstructed.
Is the cover removable?
Yes. The breathable outer cover can be removed for cleaning. Follow the care instructions included with the cushion.
Is it too firm or too soft?
It balances comfort and support. Rather than an overly soft sinking feel, the high-density memory foam gives structured everyday comfort.
Can older adults use it?
Yes. It suits reading, watching television, travelling, working or simply relaxing at home.
Does it need assembly?
No. Place the cushion on a suitable seat with its upright section against the chair back, then adjust your sitting position.
Can I travel with it?
You can carry it with you, but check the available seat space and any operator rules before using it while travelling.
Good to know
- This is a seat cushion for everyday comfort, not a medical product. Comfort and fit vary by person and chair, and there is no fixed time to notice a difference.
- Keep taking regular breaks from long periods of sitting.
- As it is made of memory foam, you may notice a smell right after unboxing. Let it air out; the smell usually fades within a few days.
- In a car, set it up only while parked, and only use it if your seat belt, controls, view and safety equipment are not affected.
- Reposition it if it shifts during use.
