Although an innerspring is one of the oldest bedtypes, they're still trendy, and it doesn't mean theyare less durable or too firm like some people think.Typically, they feature a steel coil core (supportsystem) with a padded layer, or a foam on top if it's ahybrid.
This provides you with a comfortable, flexible, and supportivesurface that'll keep you cooler than most other bed types(most notably, memory foam). A modern innerspring base also allows for natural body movement and limits motiondisturbance, which is excellent for people sleeping with a partner.
