Hello!
The TFK Joggster Adventure 2, and generally, all the TFK strollers are compatible with the conventional, solid-base Quick Fix carrycot sporting a 'classical, traditional' and 'parent-soothing' design, or the 2in1 Multi X hybrid that can be transformed into a form of a seat unit for the in-between carrcot->forward-facing seat period. The Multi X was designed for exactly what you have mentioned - moms like TFK strollers and travel systems very much (they are functional, quality, and durable), but they lack the possibility of a reversible seat. The Multi X solves this, and your child can ride facing you. However, this is only for a limited time (until your child is up to a year, a year and a half old).
I wouldn’t worry too much about safety. TFK products are high quality and designed with safety in mind. Like most of the carrycots, the Quick Fix carrycot also isn't 100% solid (to allow folding it), but it is still sufficiently safe, don’t worry there, or in the other case. The Multi X operates on a similar principle - and the edge near the head of the baby is raised, which creates a shield against the sun or cold. And when it comes to the ‘softness’ - soft carrycots are quite common, while in western countries, just strollers (no carrycot) are often used from birth - so I personally wouldn't be too afraid. It’s highly unlikely the baby will be harmed, plus - it won't be glued to the edge of the carrycot - the cushioning and padded sides offer a sufficient protection.
I'd rather try to find out if your feelings about the Multi X are too negative. If you really don’t like it, don't buy it. Otherwise, you're going to be stressed for pretty much nothing. However, if you feel strongly about having a forward-facing seat, I would recommend the Multi X for sure. Also, avoid worrying too much about your child not being able to face you as they can sense it. They can get used to it, even from the beginning - if the mother is also OK with it. They feel if you're nervous, however, and then, obviously, the child will want to sit in a backward-facing seat almost certainly. Every baby is different anyway, and usually, at the age of 10-14 months, every child should be OK with sitting in a world-facing stroller, not facing the parent (your sister's daughter is more of an exception in this case).
