Cordless blackout roller blinds

[Preggersplayspop]

My baby's cot is next to a window and I can't rejig the room layout as he shares a room with his brother and there is limited space. I want to put a cordless blackout roller blind on the window for safety reasons but struggling to find one, can anybody recommend a company that sells them?

We picked up a blackout blind in JL which pulls down on a spring - they have quite a few different designs so worth checking their site, you can limit to only blackout ones.

Someone told me about this - haven't used it myself, but at least you have no gapping, a perfect fit and no cords ...

Thank you both for replying. I would rather a blind I can just whip down (one handed normally!). The John Lewis ones look great, I don't know why I didn't try there before, been googling and looking at specialist blind companies and driving myself crazy with it.

Off to order some swatches, thanks again.
