Greentom lists it at 7 kg (15.4 lb), with a maximum child size of 20 kg (44 lb) or 110 cm (43 in), whichever comes first. Its published specifications make it a compact, lightweight option on paper, but they do not establish how it handles or holds up in everyday use.
Is the Greentom Upp Classic suitable from birth?
No. Greentom says the Classic seat is for children from six months to approximately four years; its 2022 EU manual says it is unsuitable for children under six months. For a newborn, Greentom offers a separate Carrycot configuration, described for use from birth to approximately six months. The Classic and Carrycot are different seat setups, not interchangeable age labels for the same configuration. Greentom’s current Classic product page and its 2022 EU manual provide the relevant limits.

How does the Classic fit into Greentom’s stroller range?
Greentom presents three configurations: Carrycot, Reversible, and Classic. The Carrycot is the newborn option to approximately six months; the Classic is the forward seat configuration starting at six months.
