3. Setup Instructions
Your Beautyrest mattress is shipped full-size and is not compressed. Due to its substantial components and high-quality manufacturing, it requires careful handling during setup.
3.1 Unpacking and Placement
- Prepare the Area: Ensure the room where the mattress will be placed is clear and has sufficient space for maneuvering.
- Transport: It is recommended to have multiple persons assist with moving the mattress due to its heavy and bulky nature. If available, utilize professional delivery services that offer room-of-choice placement.

The Beautyrest Prime Dream mattress is designed for immediate use upon proper setup. No special activation or break-in period is required, though initial comfort may vary as your body adjusts to the new support system.

5. Care and Maintenance
Proper care and maintenance will extend the life and performance of your Beautyrest mattress.
5.1 General Care
- Mattress Protector: Use a high-quality, breathable mattress protector to shield your mattress from spills, stains, and allergens.
- Cleaning: Spot clean any spills immediately using a mild detergent and a damp cloth. Avoid saturating the mattress. Do not use harsh chemicals or dry cleaning fluids.
- Rotation: Rotate your mattress 180 degrees every 3-6 months to promote even wear and extend its lifespan. This is especially important during the first year of use.
- Support: Ensure your mattress is always supported by an appropriate bed frame or foundation to prevent sagging and maintain structural integrity.
- Ventilation: Allow the mattress to breathe by occasionally removing bedding and exposing it to air.
5.2 Do Not
- Do not bend or fold the mattress, as this can damage the internal components.
- Do not iron on the mattress.
- Do not remove the law tag, as it contains important warranty information.
6. Troubleshooting
Most common issues can be resolved with simple adjustments. If you experience persistent problems, please contact customer support.
6.1 Common Concerns
- Initial Odor: A new mattress may have a slight odor upon unboxing. This is normal and will dissipate within a few days. Ensure good ventilation in the room.
- Adjusting to Comfort: It can take a few weeks for your body to adjust to a new mattress. Continue to use the mattress regularly to allow for this adjustment period.
- Uneven Surface/Sagging: Ensure the mattress is placed on a proper, supportive foundation. Rotating the mattress regularly can also help prevent premature wear.
- Noise: If you hear squeaking or other noises, check the bed frame and foundation for loose connections or instability. The Pocketed Coil Technology is designed for minimal noise.
