Questions & Answers

All of our cushions are sized for use on wheelchairs as well as for normal every-day use. The two cushions that are used more than others in wheelchairs are the Diffuser Cushion in Memory foam and the multi-purpose cushion.
We recommend the diffuser cushion as our most comfortable product and would be the most beneficial for you. If you feel having the coccyx portion cut out would be beneficial for extra relief around your tailbone area then I would look at the diffuser coccyx. They are the same product but just with the extra cut out portion. The other product that might be beneficial is the posture wedge. This product serves to tilt your pelvis at a slight angle and thereby encouraging a better more upright posture which can help with building core strength through the tummy. It is not as comfy as the diffuser but plenty of people get a great deal of benefit from it. If you think the coccyx relief is important then go for the coccyx wedge (which again is the same product but with a cut out for the tailbone).
Our Dura Fab covers are suede-like material made from polyester. Our Steri Plus covers are soft vinyl-like material that is water resistant.
Our posture wedge cushion is softer than our diffuser cushion because our diffuser cushions have a high-density inner core of traditional foam which provides firmer support.
This product is fine to be wiped with the Tuffie whites and the bleach solution of 1000 ppm. Steri-Plus Cover: It resists moisture and is easily cleaned by wiping down with suitable cloth and using approved cleaning products.
We have the grey Dura Fab diffuser cushion cover on our website under accessories.
Our diffuser cushion in memory foam comes in three sizes and comes with the cover in either Dura Fab or Steri Plus fabrics. Dura Fab is a suede-like fabric and Steri Plus is a water-resistant soft vinyl-like fabric.
We recommend the posture wedge as the best option for you regarding giving you some comfort and a better angle to sit on the car seat.
Yes, it should help to diffuse and spread any pressure through the cushion. It is normally a product that is very well received and will still give you some good support.
Yes, this cushion weighs 1.05 kg
The keyhole wedge cushion is specially designed for this condition, it is a firm wedge. The Coccyx Diffuser cushion or the Coccyx Wedge may also be an option. The former is the same height all over and being memory foam, very comfortable. The Coccyx wedge is much firmer but will also offer support.
No set weight limit but we normally have no issues with anyone up to 120kg. For bigger bodies please look at the diffuser bariatric which is a thicker version and could be more suitable.
The diffuser cushion will certainly offer comfort and support. We also have a bed seat you might like to look at on our website.
Yes, any of out cushion would be appropriate even the multipurpose cushion however I do feel the diffuser cushion (memory) would give you more height.
