Product Details
Handcrafted in the U.S.A., Kingsdown Crown Imperial® is where lavish sleep begins. It starts with a hand-tufted Fabrikool™ quilt that features breathable Joma Wool and gel foam to reduce heat buildup. Plus, added contouring memory foam helps alleviate pressure in the hips and shoulders.
Underneath, alpaca wool—perfectly lightweight and naturally antibacterial—is paired with airflow latex and pure cotton for enhanced breathability. Inside, individually wrapped zoned coils deliver lumbar support while an added layer of micro-coils contours and cradles your body so you can wake up every morning rested and refreshed.
Plus, exclusive Silent Partner® technology adds an invisible foam divider that separates each side of the bed for unparalleled motion isolation so you and your partner can rest uninterrupted. Elegantly hand-tufted for long-lasting comfort, this mattress looks just as luxurious as it feels to sleep on.

Mattresses last an average of 8-10 years.
How do you clean a mattress?
Cleaning a mattress is a simple step-by-step process. First, remove all bedding and covers to wash separately. Then, use the upholstery attachment on your vacuum cleaner to thoroughly vacuum the entire surface of the mattress, paying special attention to seams, crevices and edges. Then, spot-clean stains where needed using different solutions depending on the stain type. Once the mattress is clean, sprinkle a generous layer of baking soda over the surface to deodorize. After a few hours (ideally overnight), vacuum the mattress thoroughly to remove all residue.
