Jungle gym

The playground is an object available in The Sims, The Sims 2: Apartment Life and The Sims 3. It can only be used by children.

In The Sims, it appears as a miscellaneous item, is somewhat expensive, and it has a slide and jungle gym. Its description says it is regarded as a "clean and drug-free environment".

It does not appear in the base game of The Sims 2 but is added in the Apartment Life expansion pack, and is at most premade apartments and parks in Belladonna Cove. It can be found in buy mode under "Kids".

The playground returns again in The Sims 3. While only children can "Play" on the playground, in The Sims 3 and The Sims 2, teens can "Hang Out" on it. It can be found in buy mode under Outdoor Activities.

The playground is also available in The Sims (console) and The Sims Bustin' Out and can only be used by kids. The playground in the console games is the same one as the one in The Sims.

A swingset is in The Sims 2 base game, and might also fall into the playground category.

Lots of playgrounds com in expansion packs and from The Sims 3 Store.
