Quick answer
The Sandman 12" Cooling Foam is a medium-firm, all-foam mattress built for sleepers who want body-contouring comfort without overheating — a solid match for hot sleepers, couples, and anyone who likes a balanced "supportive but cushioned" feel.
How firm does the Sandman 12" Cooling Foam feel?
It's a medium-firm all-foam mattress, according to Sandman Bedding. That puts it in the most widely liked comfort zone: enough surface give to relieve pressure at the shoulders and hips, with enough underlying support that you don't feel like you're sinking. It suits back, side, and combination sleepers who don't want either extreme of plush or rock-hard.
What materials and foam layers are inside this mattress?
This is a layered all-foam build that pairs pressure-relieving comfort foam with a stable support base. As described by Sandman Bedding, the construction includes:
- Gel-swirl memory foam on top to contour to your body while helping manage heat
- HD gelswirl foam transition technology that bridges the comfort and support layers and minimizes motion transfer
- HD foam core for lasting stability and spinal alignment
- Smooth, non-quilted cooling cover designed to enhance airflow
Together, the gel-infused foam and breathable cover are engineered to help the surface feel less warm than a standard memory foam top while still cradling your body.
Does this mattress sleep cool for hot sleepers?
It's designed for cooler sleep. The gel-swirl memory foam helps manage heat as it contours, and the cooling cover enhances airflow so the surface feels less warm over the night. If overheating on traditional memory foam has been your problem, this build directly targets that complaint, though sleep temperature also depends on your bedding and room.
Is it good for couples who want less motion transfer?
Yes. The HD gelswirl foam transition technology minimizes motion transfer, so when one partner shifts or gets up, the movement is dampened before it reaches the other side. Combined with the HD foam core's stable support, it's a sensible pick for light sleepers sharing a bed.
Does it contain fiberglass, and what fire barrier is used instead?
No fiberglass. The mattress is fiberglass-free and uses a safe FR sock as its fire barrier. That matters because fiberglass fire barriers can shed irritating particles if a cover is unzipped; the FR sock approach avoids that concern while still meeting flammability requirements.
What sizes does the Sandman 12" Cooling Foam come in?
It's available in six standard sizes, with dimensions listed on the product page:
- Twin: 39" x 75"
- Twin XL: 39" x 80"
- Full: 54" x 75"
- Queen: 60" x 80"
- King: 76" x 80"
- Cal King: 72" x 84"
Who is this mattress best for?
Choose the Sandman 12" Cooling Foam if you want a medium-firm, all-foam feel that contours without trapping heat. It's a strong fit for hot sleepers, motion-sensitive couples, and shoppers who specifically want a fiberglass-free build. It's less ideal if you prefer the bounce and edge-to-edge support of an innerspring or hybrid coil mattress.
Frequently asked questions
How firm is the Sandman 12" Cooling Foam?
It's a medium-firm all-foam mattress, per Sandman Bedding. That balanced feel offers pressure relief at the shoulders and hips while keeping the surface supportive, which makes it broadly comfortable for back, side, and combination sleepers rather than catering to one position alone.
What's inside the mattress?
The all-foam build layers gel-swirl memory foam over HD gelswirl transition foam and an HD foam core, finished with a smooth, non-quilted cooling cover. The top contours and manages heat, the transition layer limits motion transfer, and the core provides stable support and spinal alignment.
Does it really sleep cool?
It's designed to. According to Sandman Bedding, the gel-swirl memory foam helps manage heat while the cooling cover enhances airflow so the surface feels less warm. Actual sleep temperature still varies with your bedding, room conditions, and personal body heat, but the build targets cooler sleep.
Does it contain fiberglass?
No. Sandman Bedding states the mattress is fiberglass-free and uses a safe FR sock as its fire barrier instead. This avoids the shedding-particle concern associated with fiberglass barriers while still providing flame resistance.
What warranty is included?
The mattress comes with a 10-year NPR warranty from Sandman Bedding. Keep your proof of purchase and follow the recommended support and care guidance so your coverage stays valid for the full term.
