Answered Questions
I am looking at the Transformer Sensory Sack, Space Explorers, and Hug (Lycra) Sleeping Bag. My kids are leaning towards the sleeping bag because they want the option of sleeping in it, but ai feel like the other two look way more stretchy and fun. Please compare/contrast these so I can have a better understanding of which to order. Thank you.
What is the difference between this Transformer Sensory Sack and the Space Explorer Sack? I'm trying to decide which one to get for my 5 year old sensory seeking son with autism.
Thank you!

My son loves this
The first time my son tried this was at school where the teacher had it from another parent whose child has sensory issues. She asked my son to check it out. He got in and immediately asked if he could use it in a specific situation that normally causes him a lot of stress. I was so impressed that he immediately identified how this could help him. Of course, I went home and got him one. Very stretchy and so far, my son hasn't destroyed it.

Love this
My nephew LOVES this product. It hugs him, he can hide in it, he can just cuddle up when he feels anxious. It is perfect for us.

I like it
My son is 4 and is reluctant to use it, but I want to keep it for future use. It's very stretchy and soft and I'm quite sure it will come in handy down the line

Transformer Sensory Sack
This this has been an amazing help for us! My son (6 years old, dx ASD at age 2), has a very difficult time keeping his body calm and staying organized. He LOVES to get wrapped up in the Sack and stretch his body against the fabric. After a particularity harrowing outing, he came home and went straight for it. He wrapped himself up and did not come out until he was calm.

The sack is a little big for my 4 year old, but he still enjoys it. Makes a nice hiding place for him. Good quality, nice stretchy fabric.

My son loves it!
My son, 12, loves this! He can become very tense, anxious, and frustrated during homeschool and doing school work. He covers his head and stretches his body out inside the Sack. This item takes care of his sensory needs and helps him to relax. We are very glad to have it. My other son wants one too!

Excellent calming environment
My son finds the transformer sack very calming! He loves the soft feel of the fabric, the pressure, and the full body wrap. i have a feeling I'll be ordering several more so he can have one nearby whenever he needs it - car, backpack, moms bag, school, church, etc

Very calming and makes him happy
My son struggles with managing his anxiety disorder on top of his sensory processing disorder which is challenging as he's faced with too much stimuli every day. This sensory sack is wonderful for him as it provides a little haven where he can curl up and relax as it provides him with constant calming pressure. He will sit in it to watch TV, read, at the computer and he will use it as he stretches and scoots along the floor. We love it!

Our imaginations transform!
No need for instructions on this item! I handed one to the kids and they immediately crawled in it and took turns playing "guess what I am"? One thought she transformed from a caterpillar into a worm, another was a super hero and another wanted to mummify himself and go to sleep! Great transformer sack!

Calms Us Down
What a great way to calm down. We love this sack. Our kids can stretch and move in it but they also like to snuggle down into it and shut out the world around them. It's perfect to use anytime. What a great name too!
