What size is it? We have a smaller cot and it took a 120x60 mattress. We've been happy with the ikea one!
Try eBay or Facebook Marketplace
@Lana it is but no mattresses xx
@Sophie I have done x
@Caroline W54 x L90cm
Is this any good? Xx https://www.cotmattresscompany.com/collections/cot-mattress-size-90-x-54-cm/products/90-x-54-x10-cot-mattress
Just get a different brand mattress. That's a standard size. Are you planning on using that cot from birth or do you have a moses basket ect? Might just be worth the wait if you aren't putting baby in it yet anyway x
@Grace ok. If you search google or amazon with those sizes you'll find something!
I bought a mini cot on wayfair and it's excellent
Try the little green sheep - they do most sizes and their mattresses are non toxic
We got our mini cot and mattress from Asda George online! And has lots of sheets options etc
I bought everything second hand, but then bought new mattresses from https://babymattressesonline.co.uk/custom-size-mattress-for-cots-cot-beds And they’ve been great!
