Sleepers look gorgeous on your bed and in your home. The shape and colours are designed to compliment what you have and like a pillow menu in a luxury hotel, they add a little touch of sleep glamour. The fabrics are high end and luxuriously soft and cooling to touch. We want you to feel pampered when you hold it. They are also easy to keep clean with a zip on/off cover. 

Sustainability means using fabrics that are sourced in an environmentally positive way. We use 100% TENCEL™ Lyocell, sustainable plant made fabric, from the Lenzing factory. The weight is from rounded glass beads to reduce plastic. 

We package each sleeper in a reusable cotton bag. The Siest flyer is printed using eco ink on recycled paper made in a building that uses solar energy. No popcorn stuffing.

We hand make the sleepers in Dublin, Ireland. We are a team. 

10% profits donated to mental health and wellbeing charities. The reason for this is simple. The “bad sleep” epidemic is so large right now that people are seeking help for mental health issues.

Restful sleep and feeling good are so linked that we want our business growth to reflect this. You are part of this story.

Women can't sleep unless their family and the people they love sleep. Children waking you up in the middle of the night, worrying about a parent with a new hip, snoring partner, peri or menopause issues. I wanted a product that would work to help everyone. A universal solution.

At our core is the drive to help more women sleep. Better.

In 2018, I couldn’t sleep. Working in Google, I was surviving on 5hrs a night. Stress, anxiety, no sleep... it was all linked. I hated that in Ireland the only options were anti depressants, sleeping pills or just "get on with it". Why would you need to hit rock bottom with sleep before there is a useful solution that works quickly with no side effects. I was inspired to create a better option.

So I designed a product to help people sleep better and feel comforted. Quickly. The sleeper doesn’t need a manual to figure out how it works. You simply hug it. And then it works to help calm your mind so you can drift off to sleep more easily. See FAQs for the science behind it.

I hope you adore your SiEST sleeper and it brings great sleep comfort to your home.
