Chicco was looking best from the research I did as can be tilted for reflux or general snuffly-ness. Also liked that it was the lightest when folded as a travel cot. The mattress looked a tad hard though.
The bednest may be worth a look too as the height is more adjustable and they can be rented directly from the site for about £70 for 6 months with a new mattress.
I love the snuzpod design but it is more expensive and seemed less flexible than other choices.
In the end we have decided on a mothercare cotbed with a sleepyhead- got 20% off at mothercare last week and can have a cotton changer and drawer that goes underneath- JL ones you don't have the option of s drawer. Bought the sleepyhead with £10 off via nct too and the LO will be safer from our inquisitive cats. If the LO doesn't settle I'm sure we can get hold of another option quickly.
