Frequently Asked Questions
Is an 8-inch mattress thick enough for adults?
Yes, for lighter adults and teens. For heavier daily use, consider the 10-inch Five Star model for additional support depth.
Does this need a box spring?
No. Place on a platform bed, a slatted frame (slats under 2″ apart), or a Serta mattress foundation.
Is the foam safe?
Yes. CertiPUR-US® certified — made without ozone depleters, heavy metals, formaldehyde, or phthalates, with low VOC emissions.
