Quick answer
The Molecule Reflex 12" Foam Boost is a four-layer all-foam mattress with a medium, cushion-firm feel — built for sleepers who want responsive contouring that stays cool and keeps the spine aligned. It's a balanced pick for back, side, and stomach sleepers who don't want to choose between pressure relief and steady support.
Is the Molecule Reflex Boost firm, medium, or cushion-firm?
It has a medium, cushion-firm feel — supportive enough to keep you lifted, yet soft enough to cushion pressure points. The Sleep Outfitters product page describes the Reflex Boost as a medium/cushion-firm mattress built from four layers of high-quality foam. Inside, an open-cell foam mimics the responsive feel of latex to provide more uplifting support and pressure relief, which helps forgive sleepers who shift positions overnight.
What foam layers are inside this mattress?
The Reflex Boost stacks four foam layers: a cool-touch cover, two airflow comfort foams, a targeted gel support layer, and a firm base. Each layer plays a distinct role in cooling, contouring, and spinal support.
- Instant Cool Cover — a blend of cool fibers that immediately relaxes the body upon lying down, helping you fall asleep faster (Mr Mattress Outlet).
- CoolVENT™ Airflow Foam — engineered with 4.5x greater airflow than traditional memory foam.
- AirTEC™ Responsive Foam — a latex-like comfort layer with 6x the airflow of traditional memory foam.
- Reflex LiftCOR™ Body Boost — hyper-targeted resilient gel bands positioned under the core for spinal alignment (Mr Mattress Outlet).
- ContourFLO™ firm base foam — the foundation that anchors the 12-inch profile (Mattress Overstock).
Does this mattress sleep cool or trap heat?
It's designed to sleep cool, pairing a cool-fiber cover with two airflow foams that move heat away from the body. The CoolVENT™ and AirTEC™ airflow foams allow heat to continually escape as you sleep, providing cooling comfort all night. If you tend to sleep warm on traditional memory foam, the breathable construction here — with 4.5x and 6x more airflow than standard memory foam — is built to keep the surface feeling fresh.
Who is the Molecule Reflex Boost best for?
The medium, cushion-firm feel makes it a versatile match across sleeping styles. The Sleep Outfitters page lists it as ideal for back, side, and stomach sleepers.
- Back sleepers — LiftCOR™ gel bands sit precisely under the core to keep the back from sinking out of alignment.
- Side sleepers — the latex-like AirTEC™ surface and pressure-relieving open-cell foam cushion hips and shoulders.
- Stomach sleepers — the firm ContourFLO™ base and targeted core support help hold the midsection level.
What sizes and certifications does it come in?
The Reflex Boost comes in six standard sizes and uses CertiPUR-US® certified foams, backed by a 15-year limited warranty. Per the Sleep Outfitters product page, it's available in Twin, Twin XL, Full, Queen, King, and Cal King. The Mattress Overstock page confirms the CertiPUR-US® certified foam construction, so you know every foam layer has been independently tested for content and emissions.
Frequently asked questions
Is the foam CertiPUR-US certified?
Yes. The Molecule Reflex Boost is built with CertiPUR-US® certified foams, as confirmed on the Mattress Overstock product page. That certification means the foams have been independently tested to meet standards for content, emissions, and durability — reassurance for eco-conscious shoppers who care about what goes into their bedroom.
What is the warranty length?
The Molecule Reflex Boost is backed by a 15-year limited warranty, according to the Sleep Outfitters product page. That covers the four-layer all-foam construction, giving you long-term confidence in the mattress over more than a decade of nightly use.
How does LiftCOR™ technology help with spinal alignment?
The Reflex LiftCOR™ Body Boost uses resilient gel bands placed precisely under the core to keep the back from sinking out of alignment, ensuring proper spinal posture. This hyper-targeted support concentrates reinforcement where your midsection needs it most, helping back and stomach sleepers stay level through the night.
Will it feel like sleeping on traditional memory foam?
No. The AirTEC™ responsive foam gives a latex-like feel, and the open-cell foam mimics the responsive feel of latex for more uplifting support and pressure relief. That responsiveness reduces the slow-sinking, heat-trapping sensation many sleepers associate with conventional memory foam.
How tall is the mattress?
The Molecule Reflex Boost stands 12 inches tall, per the Sleep Outfitters product page. That profile stacks four foam layers — the cool cover, two airflow comfort foams, the LiftCOR™ gel support, and a firm base — for balanced comfort and support.
