What is the maximum age and weight a child can ride in these single\-to\-double strollers?

Thule Sleek 2 Single\-to\-Double Stroller: The manual shows a 111 cm / 44 in and 6m\-4y range for the main seat\. The sources disagree: Albee Baby's listing gives a maximum child weight of 49 lb, as does Thule's manual, while Thule's Canadian FAQ says 48 pounds or 22 kilograms\. Cybex e\-Gazelle S: The e\-Gazelle S is from birth to about 4 years, max 22 kg in single mode and 2 x 22 kg in duo mode\. The stroller seat is for children up to 50 lb per seat unit from about 3 months; the cot is from birth to about 6 months and up to 20 lb; the cot measures 33 in L x 16 in W x 20\.5 in H and weighs 9\.4 lb\. The box includes the eGazelle S stroller and Gazelle S Cot\. Cybex Gazelle S 2: The maker says the stroller can be used from birth with the Gazelle S Cot or an infant car seat, while the seat unit is suitable from 3 months to 50 lbs; the store's listing says about 6 months for the seat, so the sources disagree on the seat's minimum age\.

Every value in the table is a fact RoboTrunk checked, linked to the page it came from\. A dash means no checked fact fills that cell\.

Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live\.

This page is published by RoboTrunk, a store built for shopping agents.

The store named on this page sells the product and ships it. RoboTrunk is not
the seller and never holds the money.

Buying works in one path. RoboTrunk's tools prepare a checkout at that store,
then hand back a short-lived link. The person approves the total; once RoboTrunk
has checked the store's total against it, the person is given the checkout link to
tap in their own browser, or, if the person prefers and gives permission, their
agent may open the link and finish there, and payment always happens on the
store's own checkout page. RoboTrunk never takes the payment or sees a card.
