I bought two mamas and papas cots, and ordered two new standard sized sprung mattresses from eBay. They arrived this morning and there is a bit of a gap between the cot and the mattress. I checked and the recommended mattress size is 62.5 x 128cms and I've only got 60 x 120.
What should I do? Is a gap of a few cms likely to be dangerous? I don't think I can get refund on tehm.
