Pick one or more traits above and we will show the strengths and watch-outs that matter for this mattress.
Choose the CliMax Hybrid if you want a firm, support-forward mattress with exceptional edges and movement. Compare a softer hybrid if you need deeper pressure relief, or a calmer surface if you are highly sensitive to partner motion.
Pressure-relief testing landed around 7.9/10, with minimal sinkage 1.33–1.39″ and about 2.8″ of comfort material. That combination can feel supportive rather than deeply cushioning, so the pressure score depends heavily on sleep position and body weight. Side sleepers who need more shoulder or hip give should compare thicker or softer comfort systems.
Sinkage measured 1.33–1.39 inches on the 10.5-inch mattress. That shallow result kept the hips level during back and stomach sleeping, while the firm surface offered less contour for side sleeping.
Peak-to-peak acceleration of 9.90–10.30 m/s² maps to 8.0/10 under our published motion scale. The surface mostly recovered in 0.196–0.204 seconds and fully recovered in 0.59–0.61 seconds, while bounce measured 15.32–15.94 inches. Those response and bounce measurements explain the lively feel but are scored separately under ease of movement.
A fixed 12 lb load creates the impact while an accelerometer records the movement that crosses the mattress.
Cooling testing landed around 8.9/10. The low 1.33–1.39″ sinkage reduces surface contact, while the hybrid build gives the mattress a more open, less enveloping feel than deeper-sinking foam beds. Hot sleepers should still weigh bedding, room temperature, and foam depth.
The raw edge-support test scored around 9.8/10, with 1.96–2.04″ of sitting-edge compression and outstanding lying-edge stability. That makes the perimeter one of the mattress's clearest strengths for sitting, sharing a smaller size, or sleeping near the side.
We measure seated compression, then check how secure the surface remains while lying directly along the edge.
The mattress recovered mostly in 0.196–0.204 seconds and fully in 0.59–0.61 seconds, while bounce measured 15.32–15.94 inches. That lively response makes position changes exceptionally easy, though people who dislike pushback may find it more energetic than calm.
The 10.5-inch build combines about 2.8 inches of comfort foam, 4.7 inches of pocketed coils, and 3 inches of support foam. That is a substantial structure, but available owner reporting says more about initial support than long-term softening.

Comfort systemTwo polyfoam layers · Top
2.75″One inch of polyfoam over 1.75 inches of transition foam creates a shallow, firm comfort system. This foam distributes load through the comfort stack. Its position, thickness, and firmness matter more than a gel infusion or branded name alone when judging contour and support.
Why it matters: Across the Emma CliMax Hybrid Mattress, pressure-relief testing landed around 7.9/10. Near the surface it contributes more cushioning; deeper in the mattress it primarily moderates the transition into the support core.
Pocketed coilsPocketed steel coils · Core
4.7″The coil unit supplies the mattress's lift, airflow, and high bounce. This is the mattress’s main load-bearing spring unit. Pocketed coils, when used here, compress more locally than connected springs while leaving open space for airflow and rebound.
Why it matters: For the Emma CliMax Hybrid Mattress as a whole, sinkage measured around 1.36″. This layer supplies most of the deep pushback for alignment, but the foams or fibers above it still determine initial pressure relief and contour.
Support baseSupport foam · Base
3″The foam base stabilizes the shorter coil unit. This foundation resists deep compression and keeps the comfort layers working on a stable plane; it is not intended to provide the mattress’s initial plushness.
Why it matters: In the finished Emma CliMax Hybrid Mattress, a 4.7-inch pocketed-coil unit sits over 3 inches of support foam. Its thickness and material quality are more relevant to long-term shape retention and bottoming-out resistance than to surface softness.
Cover and surface feelThin cover · Top
The thin surface cover adds little cushioning over the firm comfort system. As the surface textile, it chiefly affects the initial hand feel, moisture movement, and how readily heat leaves the sleeper; it supplies little of the mattress's deep support.
Why it matters: Across the Emma CliMax Hybrid Mattress, cooling testing landed around 8.9/10. Treat the cover as one part of thermal comfort rather than proof that the mattress will stay cool for every sleeper.
