Who it fits

Key specs explained for this king mattress

Size: King

This mattress measures 76 inches wide by 80 inches long. The width provides ample space for two sleepers to move without disturbing each other. You get extra room compared to a Queen size. This layout suits couples who value personal space during the night. It fits standard King bed frames and sheets. Check your bedroom dimensions to ensure the width fits comfortably in your room layout.

Thickness: 12 in

The mattress stands 12 inches tall from the floor. This height offers a substantial feel without being overly bulky. It is easy to get in and out of bed. The thickness supports the internal layers of foam and springs. You can use standard deep-pocket fitted sheets. This profile balances comfort and stability for most bed frames and platform bases.

Firmness: Medium Firm

The sleep surface feels balanced between soft and hard. It supports your spine while cushioning pressure points like hips and shoulders. This feel suits back and side sleepers who need support without sinking too deeply. It prevents the hammock effect common in soft mattresses. You get a stable surface for changing positions. Compare this to plush or extra-firm options to find your preferred support level.

Mattress Construction: Hybrid, memory foam and pocket springs

This design combines memory foam layers with individual pocket springs. The foam contours to your body shape for comfort. The springs provide core support and durability. This mix aims to reduce motion transfer while maintaining airflow. You get the pressure relief of foam with the bounce of springs. It avoids the heat retention of all-foam beds. This construction is ideal for those who want contouring without excessive sinkage.

Design and Build Specs

The Yuewanshun 12 Inch King Hybrid features a hybrid construction that pairs memory foam with individual pocket springs. According to the listing, the support system uses hundreds of stainless steel springs. Each spring works independently to target seven body zones. This layout aims to align your spine while reducing pressure on shoulders and hips. The comfort layer consists of slow rebound foam. This material is temperature-sensitive and breathable. It helps drain steam and sweat from the contact surface. The foam holds CertiPUR-US certification and contains no fiberglass. You can rest on these materials without worrying about off-gassing or hidden fibers.

The mattress measures 12 inches thick, 76 inches wide, and 80 inches long. It weighs 160 pounds. This substantial weight provides stability but requires effort to move. The design includes built-in edge support to prevent sagging at the perimeter. Motion isolation is another key feature. The combination of foam and springs absorbs vibration from tossing and turning. You will likely feel less disturbance from a partner’s movements. The unit arrives compressed in a box. You must allow 48 to 72 hours for full expansion after unpacking. This bed-in-a-box format simplifies transport through narrow hallways. The grey finish offers a neutral look that fits most bedroom decors.

Setup And Everyday Use Guide

Setup begins with unboxing a compressed, vacuum-sealed mattress. The Yuewanshun arrives rolled in a compact box, which simplifies transport through narrow hallways or stairs. You place the rolled unit on your bed frame and cut the packaging. The foam and springs then begin to expand. The listing advises waiting 48 to 72 hours for full recovery. This waiting period allows the memory foam and pocket springs to reach their intended 12-inch height. Once expanded, the mattress rests on standard bed frames. Its 160-pound weight makes it manageable for two people to reposition, though it is not designed for frequent moving.

Daily use relies on the hybrid construction. The individual pocket springs provide independent support for seven body zones. This means the springs compress only where you apply pressure. The slow rebound memory foam layer sits above the springs. This foam is temperature-sensitive and breathable. It absorbs body heat and allows steam to escape, keeping the contact surface dry. The medium firm feel offers a balance of cushioning and support. You will notice motion isolation when your partner moves. The independent springs and foam layer absorb vibrations, reducing the chance of disturbance. Edge support is built into the structure, providing a stable perimeter. The CertiPUR-US certification ensures the foam meets safety standards. It contains no fiberglass. This setup process and material combination define the everyday sleep environment.

Before You Buy This Mattress

You need a sturdy, supportive foundation for this 160-pound hybrid mattress. The listing specifies a 12-inch height, so verify your bed frame or headboard allows this clearance. Low-profile frames might not accommodate the full thickness. You should also check if your existing sheets fit deep pockets, as standard fitted sheets may not cover the 12-inch profile securely. The foam layers require 48 to 72 hours to fully expand after unboxing. Plan your bedroom layout to ensure you have enough space for this expansion. This model targets pressure relief and motion isolation. If you sleep with a partner who moves frequently, the pocket springs help reduce disturbance. However, if you prefer a very soft surface, this medium firm feel might not suit you. Compare these specs against other king options on the page to see if the hybrid construction aligns with your specific comfort needs and body type.

Check before you buy

• Ensure your bed frame supports 160 pounds and allows 12-inch clearance.
• Verify you have deep-pocket sheets for the 12-inch mattress height.
• Allow 48 to 72 hours for the mattress to fully expand.
• Confirm your bedroom has space for the expanded 76 by 80-inch size.
