The Harmony Mattress



Twin Twin XL Full Queen King Cal King
Product description

The Sage Sleep Harmony customizable organic mattress combines natural latex with pocketed recycled-steel coils for a firm feel with a bit of "spring" to it! Our firmest and most affordable customizable organic mattress.

What sets this mattress apart though is the choice between Plush and Firm pocketed coil units. The Harmony is covered in our certified organic mattress casing, with organic cotton and organic wool batting, a natural flame barrier that promotes a cool sleep.

11" height.

Handmade in USA.

Sage Sleep Harmony Natural Latex Mattress

The Harmony is designed to be both comfortable and durable. We wanted to create an organic mattress option that was more affordable without sacrificing the benefits of customization. 

A good choice for those looking for:
  • A firmer mattress
  • An affordable natural mattress
  • A firm feel that has a bit of “spring” or liveliness to it — not as dense as all-latex
  • The perfect mattress for heavier sleepers
  • A mattress made with all certified organic materials
  • Medium-firm coils with a choice of firmness in the natural-rubber top layer (plush or firm)
  • An innerspring mattress that can be used on a platform or adjustable bed without a box-spring or wood-slat foundation
  • A certified organic mattress that utilizes wool as its only flame retardant
