Product Details
✓Unbox and Sleep Tonight: This king mattress ships compressed as a mattress in a box, making delivery and room-to-room setup simple; unroll it on any flat surface and it expands quickly, ready to sleep on immediately with no noticeable chemical odor right out of the box; no waiting days for off-gassing, no airing out required; just unbox, unroll, and you are sleeping comfortably the same night
✓Right-Sized Support for King Sleepers: 12 inches is purposefully sized for king size sleepers; the 3-layer system starts with a high-density base foam for stability, adds a transition layer for motion absorption, then tops with matcha cooling gel memory foam for contouring comfort; medium firm feel (about 6 out of 10) supports developing bodies across all sleep positions; supports up to 600 lbs, comfortably accommodating king size sleepers
✓Matcha Cooling Technology for Hot Sleepers: Matcha cooling gel memory foam works with an open-cell structure to draw heat away and promote airflow; the open-cell structure circulates air continuously, reducing heat buildup for cooler sleep through warm nights and year-round; contouring design accommodates back, side, and stomach sleepers; the 600 lb capacity means this king mattress comfortably supports multiple sleepers
✓Certified Safe, Fiberglass-Free Construction: Every LIFEMENT mattress is 100% fiberglass-free; foam is CertiPUR-US certified, made without heavy metals, formaldehyde, or phthalates, meeting low VOC emission standards; the cover carries OEKO-TEX Standard 100 certification, confirming fabric is tested free from harmful substances; the cover is removable and easy to spot clean, giving you verified, documented peace of mind
✓Works in Every King Space: Standard king dimensions (80''L x 76''W) fit all standard king frames, bunk beds, trundle beds, daybeds, and platform beds; no box spring required; works on slatted frames and any flat, sturdy surface, making it equally at home in a bedroom, guest room, or master suite; backed by a 10-year warranty for long-term confidence; see the warranty card included in your shipment for full coverage details
