Introduction
Welcome to a new era of sleep with your Lull Original 5 Layer Memory Foam Mattress. This manual provides essential information for setting up, maintaining, and understanding the unique features of your new mattress, ensuring years of comfortable and supportive rest. Designed for optimal comfort and therapeutic support, the Lull mattress adapts to your body, promoting healthy spinal alignment for a restful night's sleep.
Key Features
Advanced Sleep Technology Layers

The Lull Original mattress is engineered with five distinct layers to provide a balanced blend of comfort, support, and cooling. Each layer works synergistically to enhance your sleep experience.
- Breathable Top Cover: A durable, soft stretch knit cover that allows cool air to easily pass through, promoting airflow.
- Cooling Memory Foam (1.5"): This viscoelastic memory foam layer features gel polymer beads designed to disperse heat, keeping you cool throughout the night.
- Fast-Response Transition Foam: Prevents sinking and ensures contouring support, adapting to your body's shape.
- High-Density Foam: Provides robust edge support for an expanded sleep surface and comfortable seating.
- Premium Cover: A breathable, durable cover designed with handles for easy lifting and positioning.
Cooling Comfort

Lull's 1.5-inch gel-infused memory foam top layer actively disperses heat, ensuring a cool and comfortable sleep environment. The open-cell structure of the foam enhances airflow, making it ideal for those who tend to sleep hot.
Therapeutic Support and Motion Isolation

The Lull mattress provides a medium-firm feel, offering optimal support for all sleeping positions – back, side, or stomach. Its design promotes healthy spinal alignment and significantly minimizes motion transfer, ensuring undisturbed sleep even with a restless partner.
Setup Guide
Unboxing Your Lull Mattress

Your Lull mattress arrives conveniently compressed in a box. To set it up, simply remove it from the box, unroll it onto your bed frame, and carefully cut away the plastic packaging. The mattress will begin to expand immediately. Allow 24-72 hours for the mattress to fully decompress and reach its intended shape and firmness. Any faint odor from the new foam will dissipate during this time.
Compatible Bed Frames

The Lull mattress is designed to work with nearly any bed frame. It can be placed on a flat surface with or without a box spring. Compatible options include Lull wood frames, Lull metal frames, Lull mattress foundations, platform beds, adjustable beds, and slatted bases. Ensure your chosen base provides adequate support to maintain the mattress's integrity and performance.
Operating Your Mattress
Once fully expanded, your Lull mattress is ready for use. Its adaptive memory foam layers will contour to your body, providing personalized comfort and support. There are no specific operational steps required beyond regular use.
Care and Maintenance
Cleaning Your Mattress
The Lull mattress features a removable cover that can be unzipped for cleaning. For minor spills, spot clean with a mild detergent and water. Allow to air dry completely before replacing the cover or using the mattress. For deeper cleaning, consult a professional mattress cleaning service. Avoid saturating the mattress with water.
Protecting Your Investment
To prolong the life and cleanliness of your Lull mattress, it is highly recommended to use a waterproof mattress protector. This will shield your mattress from spills, stains, and allergens, maintaining its pristine condition and hygiene.
Troubleshooting Common Issues
Initial Odor and Expansion
Upon unboxing, a faint, harmless odor (known as off-gassing) may be present. This is normal for new foam products and will dissipate within a few days. Ensure good ventilation in the room. The mattress may also take up to 72 hours to fully expand. If it doesn't seem to expand fully, ensure it's on a flat surface and allow more time.
Adjustment Period
It can take some time for your body to adjust to a new mattress, especially if you're transitioning from a different type of mattress. We recommend giving yourself at least 2-4 weeks to fully adapt to the feel and support of your Lull mattress.
