It's not just a Onesie, It's Comfort and Peace of Mind

It's not just a Onesie, It's Comfort and Peace of Mind

It's not just a Onesie, It's Comfort and Peace of Mind


We are so excited to announce that our Sensory Onesie is now available to purchase on our website.

Sewn in a particular way so that the seams feel seamless and there’s nothing that irritates,

Since launching in 2008, instead of offering you a range of off-shelf products, we have allowed our customers to create their own Onesies on our Personalised Onesie Builder, which has led us to become leaders in mass customisation.

We have always met the needs of the individual, and staying true to our beliefs, our Sensory Onesies is totally customisable too, and since Autism affects people in many different ways, our Create-your-Own Sensory Onesie is perfect.

Since our Sensory Onesie is Create--your-Own you can select everything from the size, to the fabric choices and even Add-On's.


Our Sensory Onesie is available in sizes 0-3 Months - 5 XL.
We also offer a Made to Measure Service, so if you have any special requirements, or would like us to know about any specific measurements, you can do so in our Order Instructions Box at the Checkout, and our Development Team will tailor your Onesie to you.
Size Charts are available to view on our website.


You can select which fabric you'd like for each section of your Onesie. We have a huge range of Fabrics to choose from;

Cotton T-Shirt
Organic Cotton Sweatshirt
Micro Fleece
Polar Fleece
Super Soft Cuddle Fleece
Medium Weight Cuddle Fleece
Cuddle Fleece
Premium Cuddle Fleece
Quilted Lambskin
Plush Jersey Sweatshirt
Bamboo Towelling Light Weight
Bamboo Towelling Heavy Weight
Stretch Towelling

All fabrics come in a range of different colours and patterns.
If you'd like to see and feel any of our Fabrics before ordering, you can email with the fabrics you'd like to see and the best address to send them too, and we'll put together your free Fabric Swatch Pack.

Add-On's are a great way to make your Onesie your own.
You're able to let your personality shine on our Personalised Onesie Builder.

You can choose between a standard, or full length zip. Both options are available for front and back zips – It’s all down to personal preference.
You also have the option to make it a two way zip, and even add a zip tab for extra under-the-chin comfort.

All of our Onesies now come with a Zip Cover, so the back of the zip is covered with fabric, making it soft against the skin.

You can then also choose to add a hood, ears, pockets, tail, feet and even personalisation.
