BACKREST & SEAT PAN MODIFICATIONS

Backrest Width and Height Modification

What is it? Backrests that are too large can become uncomfortable for the users, and so Ergochair offers the ability to trim down the chair to the size that you actually need. The simplest modification of the backrest is to reduce either (or both) the width and the height of the backrest.

How do you do it?

    1. Select your chair template from the Adapt 600 range
    2. Using your measurements, select your backrest width – we recommend that the backrest width is 40mm larger than the hip width
    3. Using your measurements, select your backrest height – we recommend that the backrest height is 350mm less than the shoulder height if you are using a neck rest, or the backrest height mid-range should be the same as the shoulder height if you don’t require a neck rest.

      Seat Pan Width and Depth Modification

      What is it? For the seat to be comfortable, armrests to fit properly, and for the leg to be adequately supported, it is important to ensure that the seat width and depth are the correct size for the user. The simplest modification of the seat pan is to reduce either (or both) the width and the depth of the seat pan.

      How do you do it?

        1. Select your chair template from the Adapt 600 range
        2. Using your measurements, select your seat pan width – we recommend that the width is 40mm larger than the hip width
        3. Using your measurements, select your seat pan depth – we recommend that the depth of the seat pan is 30mm less than the buttock popliteal length.

          Coccyx Cut Out

          What is it? This is the complete cut-out of the cushion that is positioned at the coccyx area.

          Who is it for? A coccyx cutout is most popular for individuals with moderate to severe coccyx pain and individuals with coccyx pain who are over 14 stone.

          Key Measurements. 140 mm Length x 100 mm Width (Bespoke cut-outs are available).

            Coccyx Zone

            What is it? The coccyx zone is an area of the seat where the normal foam has been removed and replaced with a thinner profile memory foam. The result is a subtle coccyx relief zone.

            Who is it for? Individuals with mild to moderate coccyx pain.

            Key Measurements. 140 mm Length x 100 mm Width.

              Wave Seat

              What is it? A wave seat is a seat pan where the actual length of the seat pan is asymmetric so that it can support different leg lengths.

              Who is it for? Individuals with unequal thigh length.

              Key Measurements. Minimum seat depth: 340mm.

                Thigh Support (Left, right, or pair)

                What is it? Thigh supports are inflatable cassettes that are literally positioned under the thighs. The cells can be added to help counteract a structural change in the pelvis. The inflatable cells can also be used bilaterally to reduce pressure on the coccyx.

                Who uses them: Thigh supports can be useful for muscle-wastage related conditions, coccyx pain, and structural changes to the pelvic area.

                Key Measurements: Approx. cell size is 200 mm wide x 100 mm depth.

                  Ergocore Seat Cell

                  What is it? This dual-chamber air-cell option sits inside the seat and provides a ‘reactive sit’ to gently activate your core and lower back muscles whilst cushioning your sit bones.

                  Who uses them: Ergocore seat cells are particularly useful for sciatica relief and general core strengthening.

                  What is the size? Approx. cell size: 380 mm Wide x 230 mm Depth.

                    Extra Memory Foam Layer

                    What is it? Like the backrest, it is possible to add extra memory foam layers to the seat pan. As the memory foam heats up, it will slowly adapt to the user’s body shape and redistribute weight through a much wider area.

                    Who is it used for: Most commonly for individuals who have pressure sensitive tissues in the buttock area.

                    Key Measurements? Each layer is approx. 20 mm thick (non-compressed).

                      Super Memory Foam Seat(adapt 600 only)

                      What is it? This is an extra thick layer of high-density viscos-elastic foam that offers the highest level of weight redistribution during sitting. To enhance this further and get a softer seat, you can opt for a stitched seat cover.

                      Who is it used for: Most commonly individuals who have pressure sensitive tissues in the buttock area.

                        Split Seat

                        What is it? The Split Seat option has deflecting front sections at different points and can be custom-made to the user’s measurements.

                        Who is it for? Split seats work very well when you are trying to accommodate big differences in thigh length which may be caused by pelvis resections, fused hips, or amputations. The spilt is also very useful for accommodating prosthetics.

                        Key Measurements: Min overall depth: 450 mm Min width: 410 mm

                          Air Cells for Backrest Profiling

                          Not everyone has the same shaped spine, so Ergochair developed the ability to change the 3 dimensional profile of the backrest using air cells either on their own or in combination with foam sculpting. Because these are advanced level modifications we recommend that you speak to us about what modification you need.

                           

                          Sacral Cells

                          What are they? A sacral air cell is an additional inflatable cell that can be added to the lowest part of the backrest.

                          Who does it work for? When used in combination with a lumbar support, it can be very helpful for individuals who have a low lumbar arch.

                            Reactive Lumbar Cells

                            What are they? This lumbar support has a triple chamber inflatable cassette. Not only does this offer a much wider lumbar support than the standard single support, but because the chambers are interconnected, as more pressure is placed in one cell the other cells get squeezed. The end result is that the cells can better support the spine as it is moved into different positions during the day.

                            Who uses it? The reactive lumbar cell is most popular for individuals with a long graduated lumbar arch.

                              Thoracic Cells

                              What is it? The Thoracic Cell is an additional support that can be positioned in the thoracic region, between the shoulder blades, as a way of providing additional thoracic extension support.

                              Who can use it? This type of support is most popular for individuals who tend to slump in the thoracic region, it is also popular for those with protracted shoulder blades.

                                Vertical Cells

                                What are they? Vertical support cells can be positioned at any point on the backrest to fill an area between the chair and an individual’s spine. They can also be used to provide a more general lateral support.

                                Who is it used for? This type of support is most commonly used as part of a solution to accommodate scoliosis of the spine that has led to differences in the lateral position and depth of the spine on one side of the body.

                                  Reactive Vertical Cells

                                  What is it? In this configuration, the triple air cell unit is rotated 90 degrees so it acts as a vertical support across the middle part of the backrest. Because the three air cells are interconnected, air can transit to each cell as weight is transferred across the unit.

                                  Who is it used for? This is particularly popular for individuals with lateral spine changes, such as a minor scoliosis.

                                    Foam Sculpting

                                    Foam sculpting involves literally cutting the foam on the back support; both with or without additional memory foam in order to totally personalise the profile of the backrest. Like air cell integration, foam sculpting is an advanced adaptation, so we recommend contacting us with any questions you have about this adaptation.

                                    Who is it used for? Most commonly, foam sculpting is used to accommodate changes in the spinal shape cause by Scoliosis and Kyphosis. However, because of the sheer range of profiles that can be shaped, it is possible to use foam sculpting to accommodate a vast range of spine shapes.

                                      Memory Foam Layer

                                      What is it? There are several ways we can use memory foam to change the backrest dynamics. Adding a single layer of foam provides a more supportive sitting surface that over time will gradually conform to the shape of the user’s spine. As another option, it is possible to combine a layer of memory foam with foam sculpting, which means we can provide a very precise profile that better conforms to the shape of the spine.

                                      Who is it for? Standard memory foam is most commonly used for people who have low back pain.A combination of memory foam and foam profiling is most commonly used for individuals who have some degree of kyphosis or scoliosis.

                                        Stitched Seat

                                        As part of the manufacturing process, the fabric is stretched across the seat pan and attached under the seat. The result is a highly tensioned fabric and slightly convex seat. Whilst this profile suits a lot of people, some individuals prefer a flatter profile chair and a more adaptable fabric, which is achieved through stitching on each side of the seat to have the fabric pulled over the top.
