Perfect Sleeper FAQS

Zoned comfort brings comfort where it matters most. The 850-coil density system offers three support zones with targeted support for your lower back and hips and cradled comfort everywhere else. This feature is present in the Oasis models, Midsummer Nights models and Nurture Night models.

Yes! The Quilted version of the Perfect Sleeper mattress has the new cool Feel Cover which offers a cool to the touch surface that customers will be able to experience the moment they lie down. This will help offer a cool sleep surface for perfect Cooling.

When you lay on a Hybrid mattress, it will feel more comparable to a traditional foam mattress, with the added support of a coil base. Because the foams used in the Hybrid model are mostly memory foam, that material has a slower reaction time. As you lay on the mattress, it will take a few minutes to sink into the foam and receive the pressure-relieving benefits.
The Hybrid models offer a great amount of support, but still provide the bounce you would come to expect from a traditional mattress. The Hybrid mattresses also have a flatter, more squared-off look.
