Travel cot for long term/permanent use recommendations

Does anyone have recommendations for a travel cot I can use more long term/permanently at home? We're planning to move in the next 3-4 months so don't want to get a proper cot bed in yet. I was hoping to find a decent travel cot (ideally versatile e.g. doubles as play pen) with a good firm mattress that we can use until we move. Currently considering Tutti Bambini Cozee Go 3-in-1 (as currently using Cozee Air and and pretty happy with it) or Silver Cross 3-in-1 travel cot. It would be magic if there was a travel cot with multiple height adjustments, but seems I'll have to settle with getting him in through the play pen flap if needed. LO is 4 months old today. He's currently in his next to me. We'll be away overseas for about a month next week, and I foresee he won't fit into his next to me when we return, so really seriously trying to sort the next option. Thanks in advance x
