Worth every penny in safety
Size: X-Small (Pack of 1)
This is amazing. My child’s therapist recommended this product and it is truly amazing and worth the investment. Our child has level two autism with elopement disorder. He is also a bit of a Houdini. It’s made traditional car seats unsafe for him. This device allows him. A lot of freedom to move his arms and legs without worrying about the rest of his body staying in place. They also have additional accessories to further secure the child using the lower anchor rings of the car. They also have arm and hand restraints to make transitioning from the car to outside easier and safer. I would recommend to any one with special needs children who have a tendency to be unsafe in a traditional car seat. ... show more

Great product!!!!
Size: Medium (Pack of 1)
Our son has autism and wouldn't be safe in a vehicle without constant, close-proximity supervision in which was unpossible at times being i had to travel alone with him at times , it became a huge safty consern . I was a little hesitant with spending so much money and what if it didnt really work for us , but coming across this product and purching It was a huge life changer it holds his back against the seat, while the belt keeps his waist and hips in the proper position for a safe ride for all involved. Installing it in the car was quick and easy, and getting him in and out of it is even easier . Being Our son wouldnt stay seated in his booster seat we didn’t know what we were going to do. I was searching different options on the internet to help keep him safey buckled in the car ....The timing for this find couldn’t be better. This is an excellent product and I will be telling everyone I know about it. I will definitely do business with this company again!!!! ... show more

Best vehicle item and must have for safety for everyone
Size: Medium (Pack of 1)
Nice fits all year long. Even in a jacket. Keeps everyone safe and happy. I don't have to worry about my kiddo get out of his seat. Can still use in a vehicle that did not have the back hooks to connect the harness, just use the seat belt through the bottom Loops. To keep them in their seats. They still can't wiggle out! Best vehicle item, a must item for any and all ASD that can't seat still. ... show more

Great product
Size: Medium (Pack of 1)
My child’s transportation uses this for their special needs kids. It has straps for in between their legs that lock in the back and the two upper part to latch on the clips by their shoulder. THE MECHANISM FOR THE CAR IS NOT INCLUDED. If you carefully look at the info for the product you see it’s sold separately. It’s not the only design. This one works perfectly for my autistic 8 year old who is on the bigger side (4”6 80lb). I purchased with the mechanism for the car and it arrived at the same time but it makes sense since you are buying two things it may not so plan for that. Overall great product. ... show more

I will recomend if you have a child in the spectrum.
Size: Medium (Pack of 1)
It works great to keep my child on the seat. He can't scape the seat belt anymore. We were rear ended and thanks to this product my child was sitting straight with the car steatbelt before the impact.

We love our harness!
Size: Medium (Pack of 1)
My son is 5’9 and 118lbs - we bought the med and it works perfectly. This is so freeing for him. He’s 19 but disabled and has always ridden in car seats. He LOVES his harness. Thank you for offering this little slice of normalcy to him and others.
