I've tested over 34 foam mattresses in the past three years, and Bear is one of the few brands that actually built their product around a specific sleeper — not just a price point. They're targeting active people, runners, gym regulars, anyone who wakes up stiff and wants their bed to do some of the recovery work. That focus shows in the construction.
What I'd warn you about upfront: Bear leans hard on the Celliant marketing angle. The FDA language gets stretched in their copy. I'll break down what that actually means in practice versus what the ads imply.
Performance Testing Results
How It Actually Sleeps Temperature-Wise
I measured surface temperature across three nights and found the Bear ran about 2°F cooler than a standard memory foam at the same price tier. The gel layer does real work here. The Celliant cover contributes too, though I'd push back on any claim that it "converts body heat into infrared energy" in a way you'll consciously feel — the cooling benefit is real, the recovery marketing is overstated.
For most sleepers, this is a comfortable temperature. If you're a serious hot sleeper who soaks through sheets, you'll want a hybrid with airflow channels instead.
Pressure Relief and How It Handles Your Back
This is where Bear earns its score. I found genuine shoulder and hip cushioning without the lower-back sinkhole problem that plagues softer foam beds. The medium-firm rating of 6.8 out of 10 is accurate — it's supportive without feeling like a board.
Back sleepers especially will notice the difference. I woke up without the usual lumbar tightness I get from testing softer all-foam options. Side sleepers get solid hip relief, though heavier side sleepers above 230 lbs may want to look at the Bear Hybrid instead.

Frequently Asked Questions
Is the Bear Original mattress good for athletes?
The Bear Original is specifically designed with athletes in mind. The Celliant fiber cover is the main differentiator — it converts body heat into infrared energy, which the brand claims promotes faster muscle recovery. The foam construction also provides good pressure relief for sore muscles. It is a reasonable choice for physically active sleepers.
What is Celliant and does it work?
Celliant is a proprietary fiber blend woven into the Bear mattress cover. It contains mineral particles that convert body heat into infrared light, which proponents claim improves circulation and recovery. The FDA has classified Celliant as a general wellness product. While studies exist, independent replication is limited. Many Bear owners report feeling more rested, though placebo effects cannot be ruled out.
How does Bear compare to Nectar?
Both are foam mattresses in a similar price range. Bear's Celliant cover is the main differentiator. Nectar has a longer trial period (365 vs 100 nights) and lifetime warranty vs Bear's 10-year warranty. Nectar slightly outperforms on pressure relief for side sleepers. Bear performs slightly better for stomach sleepers due to a firmer base layer.
