A few impressions of the June IRL with the following taken into account - I only played with it with the seat parent facing, mainly because I would be looking to buy it because of this feature and would plan to use it this way. If I wanted forward facing I could buy any number of other things, this was my approach.
I will start with the bad news - it is every bit as difficult to tip as up a kerb as was reported to Tiggy. That was without a toddler in. She refused to go in it altogether infact. The 7m old went in and she looked really comfy. The 5yo went in and he looked overly massive. Which is fully to be expected but he could still sit quite comfortably. He refused to let me push him. While I'm on the downsides the seat is very difficult to put on the pushchair so there will be no quick swapping pf to ff, it's not click on click off, it is tricky. Also the fold is interesting, very definitely two handed and I couldn't find a fold lock (there may be one I just didn't find) so where it might have been freestanding folded it wouldn't because it just opened up again. I liked the folded shape though, very flat, on the long side but would fit easily in most car boots.
Interestingly the shop said the instructions say you can fold with the seat on but they struggled and wanted to look at it further. I didn't have a problem, folded with the seat on no problem once I got the knack of the fold mechanism generally so I THINK it's okay on that front but I did only try with the seat parent facing. They gave me a fright saying you can't fold it with the seat on though!
On the plus side it is dinky yet robust with good suspension, lovely wheels, a nice seat that goes flatter than I remembered from last time I saw it, plenty adequate for an older baby to nap. I would say the seat is slightly higher than the bee but still on the lower side. The handle is extremely adjustable, tipping was slightly easier with it up high but still not at all easy. I'm 5'8" but tend to keep the handle fairly low, at a comfortable height for me I had to use my foot to tip it. The pushchair is extremely easy to move around folded by pulling it along with you, it's less obvious how you would carry it but the pulling is great, it's very light to pull so you wouldn't notice how much it weighs until you came to lift into a car boot for example.
Basket - fairly small. A changing bag plus little else, no big access point either with the seat pf so you might struggle to push a change bag through. The Baby Jogger Versa Basket for example was approx 3 times the size.
To be honest if you can put the size to one side for a moment and compare the June with the Versa I thought this - the price of the Versa is more sensible, it's much easier to use (you could fold it whilst holding a baby but unfolding was much more tricky.... not sure where that leaves you), has a MUCH bigger basket and it's more practical in that you can manoeuvre it up kerbs and such so much more easily. I'm not sure at this point which I would/will buy of the two, there are different considerations.
Basically as I see it the June looks fab and delivers in most areas except for tipping up kerbs and changing the seat around - both of these things would be your compromises.
Any specific questions I can try to answer but I would definitely encourage anyone interested in one to try and see one before buying!
