Overview

Nectar Ultra Memory Foam Luxury Firm Mattress 15" CalKing

Built for the sleeper who runs warm and wakes up stiff, this is the best luxury memory foam mattress CalKing size in the Nectar lineup.
4X more pressure-relieving memory foam than Nectar Classic
TriZone support layer targets shoulders, back, and hips
Temperature-regulating phase change material in the cover
Deep motion isolation keeps partners undisturbed all night
Endorsed by the American Chiropractic Association for back pain relief

The Nectar Ultra Memory Foam Luxury Firm Mattress 15" is a memory foam mattress built for sleepers who want the deepest pressure relief Nectar makes, without giving up cooling or lumbar support. At 15 inches tall, it carries four times the contouring memory foam of the Nectar Classic, plus a TriZone ergonomic support layer that delivers targeted reinforcement to your back and hips so you stop waking up stiff. The phase change material woven into the cover actively pulls heat away from the body, giving this mattress some of the best cooling performance measured in its class. If you want to feel the difference between this and competing options side by side, our sleep specialists at Mancini's Sleepworld will put you on every alternative until you know exactly what you're lying down on.

COMFORT AND FEEL: Luxury firm with deep memory foam contour and zoned lumbar support below.

SIZE: This CalKing sized mattress is ideal for couples, tall sleepers, and anyone who needs generous room to move without disturbing a partner.

BEST SLEEP MATCH: Back and side sleepers who run warm will feel right at home on this luxury firm memory foam. The TriZone support layer keeps the lumbar lifted while the deep foam cushions shoulders and hips through the night.

BEST FOR: Ideal for sleepers who overheat at night, wake up with lower back or hip tension, or need serious pressure relief without sacrificing support.

CONSTRUCTION SPECIFICATIONS: The cover's cooling fibers and phase change material actively draw heat away from the body all night. Below the surface, four inches of contouring memory foam cradles pressure points without bottoming out. The TriZone support layer underneath shifts firmness across three zones, giving the back and hips more resistance where alignment needs it most. The dense base holds everything stable so the feel stays consistent year after year. Foams are CertiPUR-US® certified.

SETUP AND COMPATIBILITY: Arrives rolled and compressed as a bed in a box, expands within 24 hours, no tools needed. Compatible with adjustable bases, platform frames, and box springs.

NOT A FIT FOR: Sleepers who prefer high bounce or easy repositioning may find all-foam memory foam too slow to respond. Edge support is moderate, so those who sit or sleep at the very perimeter may want a hybrid instead.
