Frequently asked questions
What certifications should a memory foam box mattress have?
Look for CertiPUR-US (low emissions, no heavy metals) and OEKO-TEX (harmful substances test). These ensure foam safety and durability.
How long does unpacking and expansion take?
Most mattresses fully expand within 24 hours, though some may take up to 72 hours. It's normal to have a slight smell during initial expansion.
Is a bed frame required for a box mattress?
Yes, a solid foundation like a slatted base, box spring, or platform bed is needed. Slats should be no more than 3 inches apart for proper support.
Can two people with different weights share a memory foam mattress?
Yes, but choose a medium-firm to firm model with good edge support and motion isolation. Hybrids often perform better for couples.
How long do memory foam mattresses last?
Top-rated brands last 7-10 years with proper care. Denser foams (2-3 lb/cu ft) and hybrids with coils tend to be more durable.

For most sleepers, the Nectar Mattress wins overall with its balanced comfort, lifetime warranty, and owner approval. If cooling is a top priority, the Purple Mattress excels. Budget shoppers should consider the Tuft & Needle Original for reliable value.
