Hianab Full Size Mattress 12 Inch Hybrid - Memory Foam & Pocket Springs, Medium Firm, CertiPUR-US Certified, Fiberglass-Free, Pressure Relief

Product Overview

This mattress measures 75 inches long by 54 inches wide by 12 inches thick, making it a standard full-size option suitable for single sleepers or couples with limited space. It weighs approximately 57.3 pounds, which is manageable for most adults during unboxing. The construction features a high-end knit fabric cover that feels soft to the touch while promoting airflow. Beneath the cover, memory foam layers work with hundreds of reinforced independent pocketed springs to create a hybrid system. The medium-firm rating indicates a balance between cushioning and support, which many reviewers find comfortable for various sleeping positions. The mattress is fiberglass-free and CertiPUR-US certified, addressing concerns about material safety and off-gassing. After unboxing, the manufacturer recommends allowing 72 hours for the mattress to fully expand and air out. This waiting period helps achieve optimal loft and comfort. The product ships compressed in a box, simplifying delivery through standard doorways and up stairs. Care involves regular rotation to promote even wear and spot cleaning with mild detergent. The mattress fits most full-size bed frames and foundations.

Design & Build

The Hianab Full Size Hybrid Mattress features a 12-inch profile with a layered construction designed for durability and comfort. The top layer consists of a high-end knit fabric cover that is soft, breathable, and easy to maintain. Beneath this, memory foam provides contouring pressure relief, while airflow foam with millions of micro-perforations enhances ventilation. The core support comes from hundreds of individually wrapped pocket springs, each reinforced to prevent sagging and maintain structural integrity. These springs work independently to isolate motion and adapt to body weight. The mattress edges are reinforced to prevent roll-off and extend the usable sleep surface. All materials are fiberglass-free and CertiPUR-US certified, ensuring they meet safety standards for emissions and durability. The overall design prioritizes a medium-firm feel that balances cushioning with support.

Setup involves unboxing the compressed mattress and allowing it to expand on a suitable foundation. The manufacturer recommends waiting 72 hours for full inflation and off-gassing, though many reviewers note it rises quickly. The knit cover is removable for spot cleaning with mild detergent, though full machine washing is not advised. The hybrid construction makes the mattress relatively heavy at 57.3 pounds, so assistance may be needed for positioning. The standard full-size dimensions ensure compatibility with most bed frames and sheets. Aesthetically, the mattress has a clean, modern look with subtle quilting on the cover. The lack of fiberglass addresses common consumer concerns about material safety. Regular rotation every few months can help maintain even wear and prolong lifespan.

Performance

Reviewers consistently praise the mattress for its comfort and value. Many describe it as providing a good balance of softness and support, with several noting it helps reduce aches and promotes restful sleep. The motion isolation technology receives positive feedback for minimizing disturbances between partners, contributing to undisturbed sleep. The breathable design appears effective for many users, with reports of staying cool throughout the night. The medium-firm rating seems accurate for most sleepers, accommodating various sleeping positions without feeling too hard or too soft. The mattress expands relatively quickly after unboxing, though following the 72-hour recommendation ensures optimal performance. The hybrid construction provides noticeable pressure relief, particularly for side sleepers who need contouring at shoulders and hips.

Some reviewers mention being able to feel the springs slightly, which may indicate variability in foam density or personal sensitivity. However, most find this minimal and still rate comfort highly. The mattress holds up well over initial use, with no significant sagging reported in early reviews. The weight distribution from the pocket springs helps maintain edge support, preventing the feeling of rolling off. Temperature regulation works adequately for typical sleepers, though those who sleep very hot might desire additional cooling features. The CertiPUR-US certification and fiberglass-free construction provide peace of mind regarding material safety. The bed-in-a-box delivery is convenient, though the 57.3-pound weight requires careful handling. Overall, performance aligns with expectations for a budget-friendly hybrid mattress, offering reliable comfort and support for nightly use.
