Make bedtime a pleasant experience with this Zinus Night Therapy king mattress. The generous sleep space has seven inches of high-density Base Support Foam to provide excellent support, promoting ideal spinal alignment to help avoid body aches while enhancing stability so you can climb out of bed easily. This layer also resists sagging to lengthen the lifespan of the mattress.

With a three-inch layer of ventilated Comfort Foam, this Night Therapy mattress enhances airflow to help dissipate heat and supports your hips and shoulders for outstanding pressure-point relief, helping reduce tossing and turning to improve sleep quality. The three-inch layer of memory foam contours to the curves of your body to cradle you in lavish softness while staying cool for a comfortable sleeping experience.

This pressure-relief mattress minimizes motion transfer from a sleeping partner so you can enjoy a night of uninterrupted sleep, and the luxurious knitted jacquard cover is soft and breathable to help lull you into a deep slumber.

Large, Roomy Sleeping Space

This Zinus Night Therapy memory foam mattress features king-size dimensions to offer plenty of sleeping space that you can share comfortably. Boasting a 13" height, this mattress has a welcoming thickness to let you jump in and drift away after a long day.

Choose a Foundation for Extra Support

Put this mattress on a foundation or box spring of your choice for support. Select an adjustable bed frame for personalized comfort while relaxing before bedtime, or pick one with extra space underneath if you need additional storage space in your bedroom. Slatted foundations provide stability and improve airflow to the mattress, while low-profile box springs are easier to get in and out of in the morning.

Conforming Support All Night Long

The soft cushioning and conforming support of memory foam make this Zinus Night Therapy pressure-relief king mattress suitable for side sleepers. Multiple foam layers provide plenty of pressure relief for a good night's sleep, free of disturbances from the movements of your partner.

Cool and Fresh Every Night

Featuring natural plant oil, green tea extract and active charcoal, the BioFoam layer in the mattress absorbs moisture and helps eliminate odors that build up with everyday use to keep it dry and fresh every night. The open-cell memory foam promotes air circulation throughout the mattress to wick away body heat and offers customized support from head to toe.
