The Brooklyn Bedding Spartan is a recovery-focused performance hybrid built around a concept similar to Bear's Celliant lineup -- using Far Infrared Ray (FIR) technology woven directly into the cover to promote circulation and muscle recovery while you sleep. At 13.5" tall with three comfort foam layers, a CopperFlex™ PCM cooling system, and an 8" zoned Ascension® coil core, it delivers a well-rounded performance profile.
Three firmness options make it a flexible recommendation across sleep styles. It's a strong fit for active sleepers who prioritize recovery, hot sleepers who want layered cooling, and side sleepers who want meaningful pressure relief with a responsive, coil-supported feel.

Our Ratings & Advice
We've tested over 1,000 mattresses in the last 10 years and helped serve better sleep to over 1 million shoppers. Our ratings are born out of lab-based testing and real world evaluations.
Performance Breakdown
| Category | Our Rating | Summary |
| Pressure Relief | 8 / 10 | Strong. The three-layer foam comfort system delivers meaningful contouring and pressure relief across the shoulders and hips. A competitive result for a hybrid at this height, and one of the stronger scores in the Brooklyn Bedding lineup. Firmness selection matters here -- the Soft and Medium will deliver noticeably more surface give than the Firm. |
| Cooling | 8 / 10 | Very good. The layered approach -- PCM in the CopperFlex foam, gel swirl memory foam below, and coil-driven airflow through the core -- delivers sustained cooling rather than a surface-only effect. A strong result for a thick, foam-forward comfort system. |
| Support | 7 / 10 | Good. The zoned Ascension® coil core provides solid spinal support across positions, with firmer lumbar coils adding targeted lower back reinforcement. Not the highest support score in our showroom, but well-calibrated for most average-weight sleepers across all three firmness options. |
| Motion Isolation | 7 / 10 | Good for a hybrid. The three foam comfort layers absorb a meaningful amount of partner movement before it reaches the coil system. Above average for a mattress with this much bounce and responsiveness. Couples who are highly sensitive to partner movement should still test this in-store alongside a foam-forward option for comparison. |
| Edge Support | 7.5 / 10 | Very good. The reinforced perimeter Ascension® coils provide consistent edge support across the full mattress surface. Sleeping near the side or sitting on the edge is stable and comfortable -- a practical advantage for couples who use the full width of the mattress. |
| Ease of Movement | 8 / 10 | Excellent. The responsive foam layers and coil core make repositioning natural and low-effort throughout the night. A strong score for combination sleepers and anyone who shifts positions frequently. |
Sleep Position Ratings
Final Verdict
Best For
- ✓ Active and recovery-focused sleepers who want FIR technology in the cover
- ✓ Hot sleepers who need layered, sustained cooling rather than a surface-only effect
- ✓ Side sleepers at average body weights, especially in the Soft or Medium firmness
- ✓ Combination sleepers who want a responsive, multi-firmness hybrid
- ✓ Couples who want above-average motion isolation from a coil-based mattress
Not Ideal For
- ✗ Sleepers who need the strongest possible lumbar support -- compare with zoned options in the showroom
- ✗ Couples who are highly sensitive to any partner movement -- a foam-dominant mattress will score higher here
- ✗ Stomach sleepers at heavier body weights, who may need a firmer or more structured option
- ✗ Shoppers who prioritize a lifetime warranty -- the Spartan carries a 10-year warranty
