I struggled to find any when I was looking, it was about 3 years ago. I got a John Lewis dropside cotbed in the end, given to me from a friend who bought it about 4 years earlier.
Dropsides are no longer offered for sale in USA anymore, although all are considered safe and kitemarked here in the UK. But I wonder if the lack of US market has meant manufactures don't make drop sides anymore? I don't know, just speculating.
@Kintan, no I mean a full size cot/cot bed with a dropside mechanism that lowers one side.
Great, thanks for the suggestions, have been looking at John Lewis and have also found a decent selection at BabyMore. Just wondering if there were any super duper options I'd not found I think the changes in the US have really affected the UK market, annoyingly!
They were the first 3 in the search results. To be honest I didn't even look at the cot, just copy and pasted the link.
Most retailers seem to have dropside cots avaliable though. Amazon probably will too. As RoganJosh mentions though, finding a dropside cotbed may be more difficult. Or it was when I was looking for one a few years ago.
