Thank you. I looked at ikea but I need at least 3 sides with bars as the room is tiny and 3 sides will be against the wall. Most floor beds have no sides at all and Roomix can customise (so I can ask for the bar spacing to meet UK regulations for cribs) which is good. I'm now looking at getting the same stompa mattress (S Flex Airflow) from amazon as its £50-60 cheaper than ordering it with the bed. She's still in my room at the moment but she's turning 6 months soon and moving loads in her sleep - or not sleeping like last night when I watched her contemplate kicking me in the eye 😂
I hope you have found your bed already but if you're still looking, IKEA and home box have nice options. You can even make your own.
