1. Introduction
The Beautyrest Black Series One Firm 12.5" Twin XL Hybrid Mattress combines advanced support with contouring comfort. This mattress features Triple-Stranded Pocketed Coil Technology for individualized support and motion separation, along with a cool-to-the-touch Sleep Climate Surface for enhanced temperature regulation. The patented ContourFit Design with Beautyrest Gel Memory Foam provides pressure relief, adapting to your body's unique shape.

2. Setup and Unpacking
2.1 Unpacking Instructions
- Carefully remove the mattress from its packaging. Avoid using sharp objects that could damage the fabric.
- Place the mattress on your desired bed base.
- Allow the mattress to air out as much as possible after unpacking to reduce any new mattress odor. This is a normal occurrence and will dissipate over time.
- Do not fold or manipulate the mattress in a way that could cause damage or injury.

2.2 Base Compatibility
This Beautyrest Black Hybrid mattress is compatible with various bed bases, including:
- Box Spring
- Wooden Slat
- Platform
- Adjustable Base
Ensure your chosen base provides adequate support to maintain the mattress's integrity and warranty.

3. Features and Operation
3.1 Cooling Technology
The Sleep Climate Surface features a cool-to-the-touch cover with applied surface-cooling technology. This design promotes a comfortable sleep environment by helping to regulate temperature throughout the night.

3.2 Contouring Comfort and Pressure Relief
The patented ContourFit Design allows you to nestle directly into the Beautyrest Gel Memory Foam at the mattress surface. This construction enhances comfort and provides exceptional pressure relief, adapting to your body's contours regardless of your sleeping position.

3.3 Individualized Support and Motion Separation
Triple-Stranded Pocketed Coil Technology delivers advanced, individualized support. These coils work independently to conform to your unique shape and isolate movement, minimizing disturbance from a partner's movements.

3.4 Firm Hybrid Feel
This mattress offers a firm hybrid feel, combining conforming coils with premium foams to contour to your body's shape while maintaining a solid and supportive feel. It is well-suited for back and stomach sleepers who prefer a firmer surface.


4. Maintenance and Care
Proper care will extend the life and performance of your Beautyrest mattress.
- Mattress Protector: To protect your mattress from stains and spills, it is highly recommended to use a mattress protector. This will also contribute to the overall health and lifespan of your mattress.
- Cleaning Spills: Do not apply liquids directly to the mattress. Applying liquids may stain the fabric and worsen the soiled area. Moisture or chemicals applied directly to the mattress can cause premature breakdown of the foam and damage the product.
- Spot Cleaning: For soiled areas, apply baking soda to the affected spot. Let it stand for approximately 15 minutes, then vacuum thoroughly. Repeat as needed.
- Air Circulation: Air out the product as much as possible to maintain freshness.
- Do Not Fold: Do not fold or excessively bend the mattress, as this can damage the internal components.
5. Troubleshooting
5.1 New Mattress Odor
It is common for new mattresses to have a slight odor upon unpacking, often referred to as 'off-gassing'. This is due to the fresh materials and foams used in manufacturing and is not harmful. To minimize this:
- Ensure the mattress is placed in a well-ventilated room.
- Allow the mattress to air out for several days before using it, if possible.
- The odor will naturally dissipate over time.
5.2 Comfort Adjustment
Your body may require an adjustment period to adapt to a new mattress, especially if your previous mattress was significantly different. Allow a few weeks for your body to adjust to the new support and comfort layers.
5.3 Uneven Support
Ensure your bed base is flat, sturdy, and provides adequate support across the entire mattress surface. An old or unsupportive base can affect the feel and longevity of your new mattress.
