Sitting for extended periods can significantly impact your posture. Poor posture alignment, strain on the spine and, reduced circulation can contribute to muscle weakness and tension.

the pillow is the answer for long hours in the truck on a seat that is higher under the front, with the seat cushion I can make the back of the seat higher and relieve pressure under my thighs and knees. I will definitely buy some more for home

Questions & Answers

Hi Denise i would recommend the posture wedge cushion for your requirementhttps://www.the-pillow.com.au/cushions/posture_wedge_moreMight be a good idea to show product to your surgeon just to make sure it is ok for you but i know many have purchased the products for hip related injuries and have found the posture wedge to be very beneficial.
Yes the posture wedge should be a very good option to elevate the hips either higher or lower than normal depending on the type of pain you are receiving. Generally putting hips higher in the chair will alleviate pain better. Warm regards, Brett. 03 8585 6685
Hi Deb, I think the posture wedge would be the best for sciatica as it will tilt your pelvis slightly and should reduce some of the pressure on your lower back. Please give us a call if you have some further questions and we are happy to help at any time. Warm regards, Brett 03 8585 6685
Hi Nick, Thanks for your contact and while i am not across the condition - i am thinking perhaps a posture wedge might be of assistance to change the angle of your legs and take pressure off that area by providing some pelvic tilt? Happy for you to call and discuss and i can get a bit better idea of what you are currently doing to manage things and see if there is anything we can help you with. Warm regards, Brett Parnham03 5885 6685
I would say either the diffuser cushion or the posture wedge would be the best options for sciatica. the posture wedge encourages a better posture through pelvic tilt which may be beneficial for you. The diffuser is very comfortable on any surface but not sure if that is the primary requirement for you and believe the posture wedge would be a better choice. . Please give us a call and happy to help further with any questions.
Hi Lisa, Very sorry about the delay. Our of our products i would recommend the posture wedge. This will encourage you to sit up with better posture and also help strengthen your core which will in turn help your back. You would use this on and off doing the day. A lumber roll will also probably help but you don't use at the same time as the posture wedge. A good option also is to look at the stand up/sit down desks. We all use them here and alternate between sitting and standing. We dont sell them but we use ikea versions which are very affordable and quite effective. Hope this info helps. Happy to chat further if you require.
This is a really good product. I am not sure you would want to be on any more of an angle as it may become uncomfortable to sit (although we could make it double the angle by putting two wedges together if you wished)?
The Posture Wedge Chair Cushion is a wedge seat cushion for those who need to encourage correct pelvic tilt and thereby help alleviate pressure on lumbar discs.
The posture wedge does come with a durafab (suede) or a sterriplus (waterproof) cover which in most cases is fine to use without the need for an extra cotton case. The suede version is far and away the most popular and i would recommend unless waterproof is a requirement.
The angle of the Posture Wedge encourages correct pelvic tilt to reduce pressure on lumbar discs.
I would say the posture wedge should be the best fit for you and perhaps in combination with the back huggar (our best selling back support) you might find some benefits. Often use of one product on its own is better than the using both but they can be used independently on any type of chair if using them together does not suit. Please call if i can be of further assistance.

I dont know the exact seating size of the falcon but the posture wedge is slightly smaller than most other cushions so should definitely be a good fit in most cars. Warm regards, Brett.

Hi Janeen, the posture Wedge will encourage your pelvis to tilt and this may ease your hamstring pain.The coccyx diffuser cushion is another option.Kind regards, Anmaree
Hi Carol, I would be guided by your Health Professional. The Posture wedge will encourage you to sit up straight. It is a firm cushion.

Hello, The posture wedge is very dense and will give you continued support for ages (they hold shape for many years under continued use). The thickness at the thick end is 7 cm (approx 3 inches) so product should woirk quite well for you. Warm regards, Brett03 8585 6685

The dura fab is a suede cover and suitable for all purposes unless you require waterproof which is sterri plus material. Warm regards, Brett. 03 8585 6685
Hello Susan, It should provide two distinct angles that you can sit in your car depending on what angle you wish to sit at? The product sits comfortably in most car seats also. Happy to help with any questions that you may have on 03 8585 6685 at anytime. Warm regards, Brett. 03 8585 6685
I think your best option should be the coccyx wedge. It will take pressure off during the plane ride and shuld help prevent soreness. It helps with posture too although that might not be perfect for a plane seat. I think it would be beneficial overall though. Warm regards, Brett03 8585 6685
Of course Alison . We will send through quote for you shortly. Warm regards, Brett.
Hi Anne, The cushion is made from reconstitued foam (diced up foam of different grades) meaning it is very resiliant strong but also quite comfortable. Happy to help with any further questions you may have at anytime. Warm regards, Brett. 03 8585 6685
Sorry about the delay. Both products are machine washable but only go the sterri plus if you require waterproofing for some reason. The dura fab is much more popular. Memory foam is a foam that will mold around the shape of the body rather than hold its shape in the same way as traditional foam. We only produce the posture wedge in a traditional foam as it requires a lot of support under body weight. Warm regards, Brett. (03) 8585 6685
Hello, The specifications are all correct at 42x40cm x2.6-7cm deep and the product should be great for pretty much everyone of any size. Can you tell me which brochure you found the sizing on and i can make sure we get that corrected for the next reprint. Once again very sorry for the confusion. Warm regards, Brett 03 8585 6685
Hello, Normally those two products would be used independently rather than together so i would recommend just using on their own. Warm regards, Brett. 03 8585 6685
Hi,We unfortunately do not have a stockist at present in the US, however, you are more than welcome to place an order online with us as we ship World-wide.Warm regards,Cristina
Hi Sarah,Our posture wedge cushion measurements are:42cm across x 40 cm x 2.6 cm (thin) x 7 cm (thick)Please see the link below for more information:https://www.the-pillow.com.au/cushions/posture_wedge_moreYou are welcome to also phone us on 03 8585 6685 for further information.Warm regards,Cristina
Hi Merilyn, The posture wedge should be quite suitable for the car and giving you some extra comfort by changing the angle of how you sit. We are also working on a firmer version of the product which will not suit everyone due to it being quite firm but will be very good at activating the postural muscles which should see it be very beneficiial for better posture. Please call us if you think this may be of interest. Warm regards, Brett Parnham03 8585 6685
Hi Marian,Most certainly you may use this cushion in the car.Warm Regards,Cristina
Hi Rosemary, The posture wedge size is 42cm across x 40 cm x 2.6 cm (thin) x 7 cm (thick) and the product is dense enough to give good support but not too hard as to be uncofomftable. Since you are in Perth i would recommend contacting our WA rep on 08 9381 2333 and they can recmmend a stockist nearby to you to make sure the posture wedge suits your needs. Warm regards, Brett 03 8585 6685
Hello, It is mid-range in terms of softness/hardness. Comfortable enough to not make your bottom sore but will also give good support over a long period of time. Happy to chat further on 03 8585 6685 should you have more questions. Warm regards, Brett.
Hi Sue, I would think that our posture wedge should be the right product for your pelvic tilt as that is the primary design. The product can also help with nerve problems and back related issues by changing alignment and increasing core stability. Happy to chat further on 03 8585 6685 if you would like me to answer any questions more thoroughly. Warm regards, Brett Parnham.
