“The seating Dynamics Rocker Back product has been highly effective and durable intervention for our wheelchair users with complex medical issues such as spasticity, severe extensor tone, severe self-stimulatory rocking behaviors, and history of pain and sitting intolerance.”

Joe McKnight

Retired RN, ATP/SMS, and Paramedic

“Now, in my 60’s, as a retired RN, ATP/SMS, and Paramedic, with a few hundred chairs dispensed, I’m lucky to work with Greg, his team and Michelle for some years.  We started in the Kids Up days and understood that movement was a vital, noble and normal component of humanity. In a word, don’t discount movement.”

Elaine T. Lu PT, MHEd, ATP

“The advantages to our clients who require this technology include decreased agitation, injury while in a wheelchair, loss of position in relation to the seating surfaces, active extension, and fatigue. Dynamic Seating also increases the client’s tolerance to sitting in the wheelchair. This intervention improves vestibular input, active range of motion, alertness, function, strength, and postural control.”

“Dynamic backs are essential to accommodate people with severe tone and spasticity. They are also essential to accommodate people with severe cognitive and behavioral issues who tend to rock / thrash themselves against their backrest.”

Arthur, Henry’s Dad

Portland, OR

“Again, I can’t thank you enough for speaking with me, managing Henry’s care/needs can be overwhelming at times and having you understand how complicated these things can be while actually doing something to help improve the quality of care/life for people with CP was very refreshing.”

“Darcy loves his new chair! He enjoys being able to move around and be able to leave the house frequently with carers, which he did only occasionally previously due to safety concerns and poor tolerance in his own chair.”

“I love using your RFQ app because of how thorough and timely it is. I’ve been able to put in the information I have during or right after an eval and received my quote within 24 hours if not quicker. The RFQ app is convenient and efficient.”

“We often find ourselves struggling in clinical practice when the individual we are assessing has fluctuating and/or increased extensor tone for example. Providing static solutions to dynamic bodies can sometimes be detrimental to the individual using the wheelchair and seating system. A fantastic option for many individuals presenting with a lot of movement due to tone is dynamic seating. As clinicians we can determine from our hands on assessment as well as from listening to and paying heed to the history this person has had with technology whether dynamic seating may be a consideration for successful outcomes. We can even determine at what joints the individual may benefit most from this dynamic movement opportunity, protecting the individual and the technology from damage.”

John Burke, ATP

“I have to say that I love and embrace all this technology. What worries me is the funding aspect of it which usually tends to lag behind. I have used these products with tremendous results. Don’t ever be afraid to consider these products if funding is an issue. Get with a great, forward thinking therapist and you can make this happen.”

Karen Cole Gottschalk, PT, DPT, C/NDT

“I just wanted to send one last e-mail to let you know I installed the dynamic footrests on Amber’s chair yesterday. She is very happy with how they move and work for her. It’s an amazing concept, and so beneficial for someone like her. Thanks again for all the help with getting her the correct parts.”


Kylie’s Mom
Cody, Wyoming

“Before Kylie got the Dynamic Footrests, she was constantly breaking her footrests. She was fracturing pieces of metal and everyone kept telling us ‘this shouldn’t happen.’ Getting the dynamic footrests has cut down on trips to the supplier for repairs.”

Missy Ball, PT, MT, ATP

“Seating Dynamics has excellent dynamic products that are compatible with many frames. In my experience, the dynamic back and footrests have prevented frame damage, allowed for extension of the client but with return of pelvis to effective sitting posture, reduced pressures on back, buttock and foot area, and reduced agitation on clients with SI issues. Dynamic motion has also reduced constipation issues on one of my clients.”

“I am a huge believer that seating is NOT a static activity. Many of the individuals I have the privilege of working with in clinical practice demonstrate how much they NEED to move. I sincerely hope we begin to see more dynamic options for these individuals here in Ireland because when I was working in the US, I found dynamic solutions to be essential in many situations. I have known Greg Peek for many years, and the service and quality of Seating Dynamics solutions are consistently superb.”

Luke Conway

“It is rare in these times to be able to discuss parts issues with personnel who are in a position of authority. Too many times you end up trying to discuss issues with someone halfway around the world using fractured English. Your handling of my parts request was truly outstanding, and I want to extend my appreciation and thanks for your efforts.”

“I feel the mat evaluation is critical in the recommendation for Dynamic Seating. Understanding the client’s movement patterns, including origin of tone, strength of movement and reaction to stability, helps to achieve the best outcome for the client using Dynamic Seating components.”

Jeff Freehill

“I like the comprehensive line of products offered, and the ability for the lower extremity supports to extend at both the knee and foot. Very durable product. Thank you for your contribution to Complex Rehab Technology Industry.”

“When the client can move, you can just see it on their face – they are relieved.”  More

Bert Lindholm, ATP

“As an engineering student, one of my favorite classes was Statics and Dynamics. I’ve always been fascinated with dynamic systems and now as an ATP, it’s great to see dynamic components introduced into Complex Rehab Technology (CRT). Manual and power wheelchair users with movement disorders and excessive, uncontrolled movement patterns can exert strong forces on their equipment. It’s important for us as CRT providers to allow that movement in any way we can without adversely impacting posture.  Giving users the ability to move safely reduces the likelihood that equipment will break, it reduces the risk of pressure sores and it also increases the user’s sitting tolerance of their chair. The first dynamic components available were fairly ineffective because while they allowed movement, they failed to keep the user in optimal seated alignment. With the introduction of Seating Dynamics components, the technology has advanced an order of magnitude beyond those early designs. This is because their movement most closely matches the biomechanical movement of the ankle, knee and hip joints as well as the head/neck of a seated wheelchair user. Seating Dynamics makes outstanding, functional and effective dynamic components and they continue to be a leader in the industry through innovation and by advancing the application of this technology. They are extremely durable as well and in my years of ordering from them, I have not had a single component break or fail under the constant stress of even the most active user.”

“I was recently looking for the HPCPS code for dynamic seating for wheelchair users, but I was only able to find a pediatric dynamic seating code. I know dynamic seating is used for adults as well. I am an occupational therapist by background which is why I got into policy. I want to make sure all people are getting the equipment they need. I understand that there is a new HCPCS Code effective in 2020, E2398, Wheelchair accessory, dynamic positioning hardware for back so I am revising our policy for January 2020 and will list E2398 for the Dynamic Rocker Back interface and use K0108 for the dynamic footrest and dynamic headrest hardware.”

“Kids, prior to their dynamic seating, would scream when someone carried them to their wheelchair. Now they can move and tolerate the wheelchair. Caregivers really like that.”

“I have used dynamic backs several times in the past for clients with head trauma or cerebral palsy with periods of high extensor tone that broke back canes or headrest hardware. Definitely a needed component for those clients.”

Suzanne Payne Eason, OT/L

Director of Occupational Therapy Support Services
St. Mary’s Home

“We have used many types of dynamic components on backrests at our facility and can say honestly that the only style that has been successful has been the Seating Dynamics backrest interface. Not only is it sturdy and holds up well for longer periods of time, it easy to maintain and adjust for changes.”

Sharon Sutherland (Pratt), PT

“Once we identified what movement patterns needed to be blocked and which movements were better being allowed to happen- it was simply amazing how these children and young adults responded!! They were much more calm, slept better, had less digestive challenges and above all else  “seemed happy – more smiley and less tears.” I am a big advocate of dynamic seating for that person who, upon thorough assessment and trial, is identified as a suitable candidate.”

Jill Sparacio, OTR/L, ATP/SMS

“The Dynamic Rocker Back option offers a dynamic seat- to-back junction.  As Derrick extends at his hips, the movement of the base eliminates solid resistance.  Instead of his movement and tone increasing (as it does with solid resistance), his movement was now facilitated, allowing his tone to calm down. The use of the Dynamic Rocker Back was successful in providing postural assistance to his active tone patterns. Of utmost importance was his need for a system that is durable and reliable.  Funding for repairs is not always available.  If Derrick’s system is broken, it results in him missing outings from which he gains a great deal of enjoyment.”


Daniel’s Mom
Centennial, CO

“If it weren’t for Seating Dynamics my son’s knees would still be swollen & bruised and he would still be breaking wheelchairs by shearing screws in half when he pushes with his high muscle tone. The moving parts allow him to be comfortable for longer periods of time and alleviates his pressure points, along with more options for positioning adjustments.”


Robert’s Dad
Los Angeles, CA

“His positioning in the chair is much better than what we have been able to provide in the past.  This facilitates his endurance, his comfort, and his ability to use augmentative communication devices. He seems more relaxed in his body, and therefore able to be more attentive with his mind. The fact that the Rocker Back reduces wheelchair breakages saves us time and emotional energy, gives us one less thing to stress over, and actually allows us to go enjoy life more often.”

JJ Waldrop, ATP

“I have tried several different manufacturers of dynamic components over the years but all pale in comparison to the products put out by Seating Dynamics. Products and customer service is top notch and their products have held up in the most extreme situations when configured properly. They are my go to for dynamics.”

Mark Locklear, ATP

“Dynamic Seating allows for better postural alignment without having to reposition the client multiple times throughout the day. I like the multiple dynamic options (dynamic footrests and dynamic rocker back) to accommodate many obstacles with clients who have cerebral palsy in many of our day programs and residential homes. Specifically allowing clients to have functional movement has reduced the amount of extension patterns in several clients of mine.”

“The use of a dynamic headrest on this kind of patient should be the standard, not just to protect the equipment, but the patient.” Referring to clients who repeatedly contact their head support with significant force.

“What an amazing addition to our world!! The dynamic foot rests have changed my son and our family’s every day for the better. For years we have struggled to find a dynamic foot rest that could absorb my son’s remarkable and incessant spasticity in order to keep him seated properly and prevent orthopedic and respiratory concerns. We could see a HUGE difference right from the start. The need to reposition him every few minutes was almost completely gone. The support of the company has also been amazing for our many questions and concerns. We can’t wait to see the next dynamic products developed!!” (Quote from the client’s Mother)


Hannah’s Mom

“I loved that I could add it to her existing chair without changing the whole system. The DRBi is the best purchase I’ve ever made for Hannah.”
