Lull Premium Mattress Construction
The Lull Premium Mattress is designed to offer ample support without sacrificing comfort. Read on to learn more about the construction of this mattress.
Quilted Memory Foam Cover
First, there’s the 1” quilted memory foam cover with hexagonal top-tick. The open-cell foam enhances the contouring and cushioning effects of the other comfort layers. It also prevents overheating by allow air to circulate through the foam. The cover has a neutral color that is easily concealed by sheets.
Cooling Comfort Layer
Speaking of keeping cool, the next layer of memory foam is infused with cooling gel beads. This 2” layer draws heat away from your body and provides pressure relief. It also helps maintain proper spine alignment.
Fast Response Transition Layer
A 2” layer of medium-firm foam adds support and durability. This highly responsive foam evenly distributes motion and eases the transition to the high-density base layer. Like the previous layers, the transition layer helps maintain spinal alignment.
Durable Base Layer
A foundation layer of high-density foam prevents sagging and enhances the lifespan of the mattress. This 7” layer adds support to the comfort layers and durability to the Lull Premium Mattress.

Premium Cover
The Premium cover gives the Lull Premium Mattress an attractive finish. With channel stitching and a neutral color, the cover won’t show beneath sheets.
Medium-Firm Feel
The Lull Premium Mattress combines support and comfort for a medium-firm feel. That’s a rating of 5-7 on a firmness scale of 1 to 10, with 10 the firmest. A medium-firm mattress is generally a good choice for back and stomach sleepers. It may be a bit too firm for lighter weight side sleepers, but that ultimately depends on personal preference.
Premium Mattress Size Selection
All sizes of the Lull Premium Mattress measure 12” high. The mattress is available in the following standard sizes:
- Twin: 38” x 75”
- Twin XL: 38” x 80”
- Full: 54” x 75”
- Queen: 60” x 80”
- King: 76” x 80”
- California King: 72” x 84”
Lull Premium Mattress Review: Pros and Any Limitations
Our team has researched and reviewed the Lull Premium Mattress. In our opinion, it’s advantages and any limitations are as follows:
Contouring Comfort Without Sinking
Four layers of foam provide contouring comfort along with plenty of support. The quilted memory foam cover and comfort layer cradle your body and relieve pressure in your spine and joints.
Made of medium-firm foam, the transition layer keeps your spine properly aligned. This firmer layer is important because it prevents your hips, shoulders, and midsection from sinking into the mattress and throwing your back out of alignment.
Finally, the high-density base layer adds durability and more support. As it prevents sagging, it maintains the evenly distributed support and comfort of the previous three layers.
Lets You Sleep Cool
Advanced cooling technology lets you enjoy ultra-comfortable memory foam without waking up hot and sweaty. First, the quilted cover is made of breathable, open-cell foam. Unlike traditional memory foam this layer won’t trap body heat. Air flows through the breathable foam, carrying heat away from the mattress.
Just below the quilted cover is a memory foam layer that keeps you cool. Infused with gel beads, this comfort layer draws away heat. We like how the comfort layers keep you cool as they cradle you to sleep.
Great for Back and Stomach Sleepers
The Lull Premium’s medium-firm feel is ideal for those who sleep on their stomach or back. These sleep positions require enough support to prevent the midsection from drooping lower than the rest of the body. Thanks to the responsive transition layer and high-density foam base, the mattress keeps your spine and midsection aligned.
If you sleep on your side, you may find the mattress a little too firm. Of course, the best firmness level for an individual is a matter of personal preference.

Safety Certifications
It’s good to know that the mattress you sleep on is made of planet-friendly, nontoxic materials. The Lull Premium Mattress has received multiple safety certifications and sustained memberships. The CertiPUR-US® certification means that the foams in the mattress are free of ozone depleters as well as harmful chemicals and heavy metals.
Lull is a member of the Sustainable Furnishing Council® and the Mattress Recycling Council®. These memberships show a commitment to reduced carbon footprint, lower emissions, and efficient packaging.
Conveniently Delivered In a Box
Who doesn’t appreciate a little convenience when shopping for the best mattress in a box? Instead of driving from store to store and waiting around for a delivery team, all you have to do is wait for your Lull Premium Mattress to arrive in a box.
According to their website, Lull uses innovative compression technology when preparing the mattress for shipment. The process preserves the integrity of the foam and ensures optimal bounce-back after unboxing.
You may have to wait a bit before using your new Lull Premium Mattress. Most foam mattresses require up to a few hours to expand to full size. There may also be a slight, harmless odor that should dissipate after a few hours of airflow out.
Generous 365-Night Sleep Trial
It can take at least 30 days to adjust to a new mattress — much longer than a few minutes in a furniture showroom. We’re impressed with Lull’s 365-might trial period. You get an entire year to try your mattress at home, taking much of the stress out of buying a mattress.
Lull recommends a 30-day break-in period before you decide whether to keep the mattress. If the Premium Mattress just isn’t working for you during the 365-night trial, Lull will arrange a free pickup and give you a refund.
Lifetime Warranty
We also think you’ll like the Lifetime Warranty that comes with the Lull Premium Mattress. The warranty covers manufacturing defects such as a damaged cover or visible indentations deeper than 1.5”. Defects must not be caused by improper use or handling of the mattress.
If Lull finds that your mattress has a qualifying defect, the company will repair or replace the mattress. We recommend reading the warranty terms before buying, because a warranty policy can change at any time.
Concluding Thoughts on the Lull Premium Mattress
The Lull Premium Mattress combines four foam layers of varying firmness to create a medium-firm mattress. Using advanced memory foam and cooling technologies, the mattress stays cool as it offers comfort and support.
We like the combination of memory foam with responsive transition foam and high-density base foam. The result is a medium-firm mattress that helps maintain spine alignment as it cushions your body. We think that back and stomach sleepers will find this to be an optimal combination. The supportive transition and base layers offset the contouring layers with support and stability.
As the memory foam contours to your body, cooling materials prevent overheating. The quilted memory foam cover is made with breathable, open-cell foam, while the memory foam comfort layer contains cooling gel beads. The layers of foam draw away heat and regulate temperature all night.
These foam layers are good for the planet as well as for your comfort. CertiPUR-US® certification means that the foams need strict safety and environmental standards. Lull is also a member of the Sustainable Furnishing Council® and Mattress Recycling Council®.
Convenience is always welcome, so we think you’ll appreciate having your Lull Premium Mattress shipped in a box, directly to your door. Receiving your mattress in a box means less hassle for you. Within a few hours, a foam mattress is usually fully expanded and ready to use.
Lull stands by their mattress in two ways: a 365-night sleep trial and a limited lifetime warranty. The sleep trial is much longer that mother trial periods and gives you a chance to be sure about your purchase. The lifetime warranty recognizes that even the best mattress in a box can occasionally have manufacturing defects. We applaud Lull’s willingness to back their product in this way.
Our research and review leads us to believe that the Lull Premium Mattress is a quality mattress in a box. In our opinion, it offers value to consumers.
