I can't remember if the Gluxe has a full recline or only a partial recline. Otherwise I believe it meets your other critera (besides taking a car seat).
The Baby Jogger City Mini single (3-wheel) has an optional adaptor for the Cybex car seat and weighs about 17 lbs. It also has a full recline. The sun shade is amazingly large and the stroller folds flat. It meets your other criteria as well. Ours has served us very well during the past 4 years.
