A first look
at their cozy.
my little evening spot now
Added my usual cushions and blanket and honestly... I spend more time here than on the sofa now 😂 really like having something soft to lean against.

Not exactly a showroom bed lol
Mine usually looks like a pile of blankets anyway, but this makes it feel like a proper little nest. I like that I can still use all my own bedding.

this is where you'll find me
Big duvet, lights down, phone away. That's pretty much my evening sorted. The soft sides are def my favourite bit.

Looks messy. Feels amazing.
Wasn't sure I'd like having edges around the bed but I actually love curling up against them. My photo isn't doing it any favours 😅 it's SO soft.

Apparently I bought it for the cats
Hadn't even finished making the bed and these two moved in 😂 I get the appeal tbh. The borders are lovely and soft.

Comfy, just a bit wrinkly
Really like the soft edges. The cover looks a little creased on my bed, which is why I've gone with 4 stars. Once the duvet's on I barely notice it though.

The purple bedding was staying!
Still feels like my bed, just cosier. Love the little tucked-in feeling round the edges 🤍

Sharing is apparently mandatory
Love the cozy feel. Would probably choose darker bedding next time because the cat hair shows up on everything 🙃 but that's more a me-and-my-cat problem.

Didn't have to change my whole setup
Kept my big pillow and comforter, just added the Cocoon underneath. Really like the cushioned edge when I'm sitting up in bed. Simple thing, but it's my favourite part.

A LITTLE CLARITYGood questions.
Good questions.
Soft answers.
The things you might be wondering before you climb in.
Ask us anything ↗What exactly is the Cocoon?
A plush fitted mattress cover with four padded foam borders. It adds a soft perimeter to your own bed, giving you somewhere cozy to lean, curl up and unwind.
What comes with my Cocoon?
One fitted plush cover and four removable foam border inserts. Your mattress, pillows and duvet are your own. A complimentary sleep mask is included with your Cocoon.
Can I use my own bedding?
Yes. Lay your favourite flat sheet over the Cocoon and tuck it beneath the borders. Add your own pillows and duvet to make the nest yours.
How do I wash it?
Remove all foam inserts first. Wash the fabric cover cold on a gentle cycle with mild detergent. Air dry, or tumble dry low if needed. Let it dry fully before reassembling. Do not bleach, iron or dry clean.
How do I choose the right size?
Match the Cocoon to your mattress width and length. It fits mattresses up to 14 in deep. See our size guide, or send us your measurements if you need a hand.
How does the 30-night sleep trial work?
Your Cocoon comes with a 30-night sleep trial, so you can find your cozy on your own bed. Contact our team if you need help during your trial.
