• 9" depth
• Recycled steel Bonnell spring at the core with a 3” layer of soft dunlop organic latex rubber on top.
• Above and below the spring is a layer of coir
• Entire mattress is covered in organic cotton fabric quilted to organic wool (NOT a zip off cover)
• Medium Firm feel

Editors note: We love Savvy Rest. Because of the layer of latex, this innerspring is a bit softer than some others. Another great Savvy product covered with their excellent warranty and great customer service, however, this innerspring does not work for someone who needs to stay latex-free.
