Last night I was sweating through a muggy summer night. This morning I'm climbing into bed like it's an igloo. Swing that far in either direction and your sleep takes the hit, usually as a 3 a.m. wake-up. That's why every top mattress we've tested has had to pass rigorous temperature regulation checks.
The best cooling mattresses pull heat away from your body with materials designed to dissipate it, which is how they fend off night sweats and heatwaves. Of all the cooling beds we've put through their paces, the Bear Elite Hybrid is the best. But it isn't the only high-tech option worth a look.
I've recently spent time with the Eight Sleep Pod 6 and the Orion Sleep System. Both are among the best smart mattresses on the market, and both use active cooling to hold the surface at a steady temperature. They perform well. They also cost a lot. So with Black Friday mattress and sleep sales approaching, which one should you actually buy? Here's my answer, based on hands-on testing of all three.
Type: Smart mattress cover. Sizes: 6 (twin–Cal king). Sleep trial: 30 nights. Warranty: 2 years. Subscription: Yes (from $17/month). Price (on sale): From $1,899 at Eight Sleep
Type: Smart mattress cover. Sizes: 3 (queen–Cal king). Sleep trial: 30 nights. Warranty: 2 years. Subscription: Optional ($250/year). Price (on sale): From $1,795 at Orion
Type: Hybrid mattress. Sizes: 7 (twin–Split king). Sleep trial: 365 nights. Warranty: Limited lifetime. Subscription: No. Price (on sale): From $1,298 at Bear
Price and deals
- The Eight Sleep and Orion are premium smart mattress covers
- The Bear Elite Hybrid is an upper mid-range hybrid mattress
- Eight Sleep requires a subscription, Orion and Bear don't
The Eight Sleep Pod 6 is the priciest of the three, with a queen listed at $2,899 MSRP. The Orion comes in cheaper at $2,395 MSRP. The Bear Elite Hybrid lists at $2,284 for a queen, but Bear runs regular sales that can push that as low as $1,370.40 through Bear's mattress discounts.
Here's the catch that matters: the Pod 6 and the Orion are covers, not mattresses. You'll need a bed you already own. The Elite Hybrid is the only one of the three that's a complete mattress.
The Pod 6 costs the most upfront, and it's also the only one that demands a subscription. At $17/month, the plan covers sleep tracking and is required to run the Pod at all. Orion offers an optional sleep tracking plan, but it's pricier at $250/year. Bear doesn't charge a subscription.
Pod 6 (queen): was $2899 now $2699
The Pod 6 launch brought twin sizes to Eight Sleep's lineup, which is good news for solo sleepers. A twin now runs $1,899, down from $1,999, and larger sizes get $200 off. Eight Sleep rarely runs big sales, so this drop stands out. I'd still expect more discounts before Black Friday.
Sleep System (queen): was $2395 now $1795
A queen smart cover under $2,000 is a rare find. Orion's Black Friday sale takes up to $600 off this climate control system. Sizes are thin, though. As of writing, you can only get queen, king, and Cal king. The price is excellent, but a deeper cut is unlikely, so if you want this one, don't wait.
Elite Hybrid (queen): was $2284 now $1370.40
For a cooling hybrid with a luxury pillow-top, the Elite Hybrid is priced competitively. Bear usually discounts 30%, and a 35% holiday sale tends to show up reliably. Right now, though, the code TOMS40 gets you 40% off plus free accessories at checkout, bringing a queen down to $1,370.40.
Design
- Eight Sleep and Orion are mattress covers with control towers
- Eight Sleep's tower is smaller and quieter, Orion's is more chic
- Bear Elite is a hybrid mattress with foam and coil layers
The Pod 6 and Orion each arrive in two pieces: a cover and a control tower. Water pipes run through the cover, and a tube links it to the tower. The tower is where the two systems differ most. Orion's is bigger and bulkier, but it has the more design-forward finish. The Pod 6 tower is the quieter of the two, which matters if you're sleeping a few feet away from it.
The Bear Elite Hybrid is a different animal entirely. It's one of the best hybrid mattresses you can buy, built from layers of springs and foam. The cover is woven with Celliant fibers that draw heat away from the body, and a copper-infused foam layer adds more temperature control underneath.
Comfort and support
- Eight Sleep and Orion don't change the feel of the bed underneath
- Bear Elite Hybrid comes in three firmness levels for all sleep styles
- A Medium Bear Elite Hybrid is ideal for side sleepers
Neither cover is meant to alter how your mattress feels. I tested both over a Leesa Original mattress, and that matches what I found. Your comfort still depends almost entirely on the mattress beneath.
The Bear Elite Hybrid impressed me on support and cushioning. It's one of the best mattresses in a box available, and it comes in three firmness levels. I tried the Medium, which has become one of my favorites for side sleeping. That range covers nearly every sleep style.
Temperature regulation
- Eight Sleep offers rapid cooling, with controls on the mattress
- Orion is app-based, warming and cooling based on ambient feel
- Both are intuitive designs with active climate control
- Bear Elite Hybrid uses cooling fabrics to maintain a neutral feel
Eight Sleep and Orion both go after temperature regulation head-on. Each is an active system that pumps water through small pipes built into the cover, so the surface stays at a consistent temperature. Eight Sleep puts its controls on the mattress itself and cools quickly. Orion takes an app-based approach and adjusts warmth and cooling based on how the bed feels.
In practice, both worked. I slept on the Orion during the shift from summer to fall, which meant some nights had every window open and others had me reaching for the heat. Right now I'm using the Pod 6 on frosty nights. Both kept the bed in the "snug" zone, well clear of "shivering" or "sauna." I haven't had a sweaty 3 a.m. wake-up in months.
The thermal camera tells the story most clearly. The Orion held a steady surface the whole time, with no temperature swings even as tester Frances Daniels climbed on. Normally a body-shaped heat outline lingers long after someone gets up. On the Orion, every trace of Frances disappeared within minutes.
The Bear Elite Hybrid takes a more conventional route. That said, with Celliant fibers and copper-infused foam, calling it simple would be a stretch.
Here's the surprise: without active cooling hardware, the Bear still didn't hold onto heat. It warms up fairly quickly, but it sheds that heat just as fast. Four minutes after our tester got off, the surface had nearly returned to its starting temperature. For most sleepers, that's the number that matters.
The Bear Elite Hybrid is a strong bed, but it can't match the Eight Sleep or the Orion Sleep System on versatility. If speed is what you're after, the Eight Sleep is hard to beat. Its buttons sit on the side of the cover, so you can change the temperature mid-night without unlocking your phone.
Eight Sleep vs Orion vs Bear Elite: Where the Features Split
- Eight Sleep delivers detailed, accurate sleep tracking
- Orion's sleep tracking is good, but shallower
- Eight Sleep includes a built-in smart alarm
Both Orion and Eight Sleep bundle sleep tracking with their active cooling. The real difference is how you pay for it. Eight Sleep's tracking comes with a mandatory subscription. Orion treats it as an optional add-on you can skip.
I tested both next to my Oura Ring 5, which is the top-rated sleep tracker we've picked this year. I came away impressed with the quality and accuracy of the data. Both systems logged sleep stages and duration that matched the Oura and my own memory of the night. That's a higher bar than it sounds, because a lot of mattress-based trackers drift from reality.
Accuracy is one thing. Depth is another, and that's where the gap opens up. The Eight Sleep Pod 6 captures a huge volume of data and presents it in graphics you can actually read at a glance. Orion's tracking, by comparison, feels like something bolted on. With Eight Sleep, the tracking is the core of the product. Here's the thing: if you care about the numbers, that distinction matters more than any single accuracy test.
The alarm tells a similar story. The Eight Sleep has a smart alarm built into the cover that vibrates when it detects a light sleep stage, so you're woken at a lighter, easier moment. Orion eases you awake with gentle warmth, which is pleasant but less effective. The Pod 6 is simply better at getting you up.
Eight Sleep vs Orion vs Bear Elite: Which One Should You Buy?
Buy the Eight Sleep Pod 6 if...
✅ You get hot flashes: The Pod 6's hot flash mode is designed to counter sudden temperature swings quickly. It should kick in while you're asleep, but you can also switch it on in the app the moment you feel one coming.
✅ You want detailed sleep tracking: Autopilot produces accurate, detailed sleep data and turns it into clear graphics, so you can spot trends and changes without digging through spreadsheets.
✅ You want control at the touch of a button: Press the button on the side of the cover to raise or lower the heat during the night. The Eight Sleep can't read your mind, so this lets you dial it in to what you actually need.
Buy the Orion Sleep System if...
✅ You want smart cooling without the premium price: On temperature control, Orion matches the Eight Sleep and the Bear Elite Hybrid, and it delivers active cooling for less money.
✅ You and your partner never agree on the thermostat: Orion and Eight Sleep both let you set a different temperature on each side of the bed. Orion gets you that split for a lower price.
Buy the Bear Elite Hybrid mattress if...
✅ You need a new bed: Choosing Orion or Eight Sleep means either buying a new mattress or keeping the one you already have. The Bear Elite Hybrid isn't only about cooling. It's a good bed all round, so it covers both jobs in one purchase.
✅ You don't suffer major temperature swings: If you wake up a little stuffy but heat isn't wrecking your night, you probably don't need high-tech active cooling. The Bear keeps you comfortable without the added cost.
The verdict comes down to two questions: how much you'll pay for control and data, and how badly you sleep hot. If the answer to the second is "not much," the Bear is the smart buy. If you want the sharpest tracking and the quickest adjustments, the Pod 6 earns its price. And if you're on a budget with a partner who runs warm, Orion is the one that makes the most sense.
