The Royal Grove models within the Spinal Comfort Collection combines an organic cotton cover with the highest quality natural latex, eco-memory foam, and our exclusive Diamond made 744 individually wrapped coil system in order to help you fall asleep faster, stay asleep longer, and wake up feeling refreshed. The Royal Grove beds do not transfer motion between partners allowing you to sleep throughout the night and receive deeper, more rejuvenating rest. These beds also reduce tossing and turning through the pressure-relieving support of our luxurious Eco-Flex plant-based comfort layers.

Made in USA!

Mattress Features & Benefits

  • Gently conforms to your body for a personalized fit by using our exclusive, individually-wrapped coil spring system
  • Reduces tossing and turning at night by allowing each coil to move independently and relieve pressure points
  • Your partner's movements will leave you undisturbed and sleeping soundly because our exclusive spring units do not transfer motion
  • Combines pressure-relieving, hypo-allergenic, natural latex and pressure-absorbing visco memory foam to reduce pressure points
  • The foam-encased design provides a supportive, firmer edge that allows you to sleep all the way to the edge of the bed without feeling like you will roll off. It increases the sleeping surface and reduces vibrations. Also, all of our foam-encased beds feature Tri-Zoned Lumbar Support to give you additional support in your lumbar region, where you need it most.
  • Maintains a cool, balanced temperature throughout the night, allowing muscles to breathe and heal
  • Minimizes pressure points to reduce pain and tossing and turning by combining layers of our Eco-Flex plant-based cushioning foam over our spring system
  • Always returns to its original shape to support you night after night
  • We process all the materials right here at Diamond, so we know they are the best and we can offer a 20 year warranty that we have stood behind for 4 generations*


A unique collection, the 3 comfort levels offered by the Royal Grove models offer the pressure relieving and hypo-allergenic benefits of Talalay Latex with the high conformability found in our eco-memory foam. The support offered by our Diamond-made, individually-wrapped coils allows for no motion transfer between partners and conforms to create a custom fit to relieve pressure.
