Yawnder Reviews · Updated July 2026
Sleep Number‘s late-2025 rebrand collapsed a decade of confusingly-named c, p, and i models into four beds: ComfortMode, ComfortNext, ClimateCool, and Climate360. If you searched for a c2, p5, i8, i10, cp8, or cA5 and landed here — those names are gone. Here’s what replaces them and how to pick.
Quick take
- The 4 models: ComfortMode (entry) · ComfortNext (mid) · ClimateCool (cooling) · Climate360 (flagship active climate)
- Only cooling models: ClimateCool (passive) and Climate360 (active)
- Best value: ComfortNext — the biggest feel upgrade for the smallest price jump
- Skip the lineup entirely if: You want a traditional pillowtop or hybrid — Sleep Number is uniquely about dual firmness
The 2026 lineup at a glance
| Model | Starting price (Queen) | Cooling | Best for |
|---|---|---|---|
| ComfortMode | ~$1,600 | None | Budget-minded couples with mismatched firmness needs |
| ComfortNext | ~$2,800 | None (passive cover) | Side sleepers who need real pressure relief |
| ClimateCool | ~$4,000 | Passive (phase-change cover + graphite foam) | Hot sleepers who don’t need active climate |
| Climate360 | ~$10,000 | Active heating + cooling with airflow | Extreme hot/cold sleepers, hormone-related night sweats |
ComfortMode: the entry
The bed most people picture when they think “Sleep Number.” One air chamber per side, foam cap on top, decent SleepIQ tracking. It’s a genuinely useful mattress if you and your partner disagree on firmness — nobody else in the industry solves that problem this well at this price. If you both sleep the same way at the same firmness, a premium hybrid at the same money buys more mattress. Full ComfortMode review →
ComfortNext: the sweet spot
Where the lineup starts feeling premium. Thicker comfort layers, higher-density memory foam, and a cover that actually looks like it belongs on a $3,000 mattress. This is the tier we’d recommend to most Sleep Number shoppers who don’t sleep hot. Full ComfortNext review →
ClimateCool: for hot sleepers
Adds a phase-change cover (cool to the touch when you get in) and graphite-infused foam that conducts heat away. Not active cooling — but effective, especially at sleep onset. Compared to a cooling hybrid at the same price, you’re paying for the adjustability. Full ClimateCool review →
Climate360: the flagship
The only Sleep Number with active climate — the mattress can heat you up on cold mornings or actively pull heat out overnight. It works. Whether it’s worth $10k+ is entirely about how badly you’re suffering. For people with hormone-related night sweats or partners with opposite temperature preferences, Climate360 is unique in the industry.
Which one should you actually buy?
- You disagree with your partner on firmness, budget matters → ComfortMode
- You want the mid-tier upgrade that actually feels different → ComfortNext
- You wake up warm → ClimateCool
- You wake up in a puddle, or your partner freezes while you burn → Climate360
- You want the best mattress at the best price and dual firmness isn’t a requirement → Skip Sleep Number and shop premium hybrids. Come try what we recommend →
What all four have in common
- DualAir chambers with 0–100 firmness adjustment on each side
- SleepIQ tracking — restlessness, heart rate, breathing rate, sleep stages
- Compatible with FlexFit adjustable bases (head/foot articulation)
- 100-night trial with a $199 restocking fee
- 15-year limited warranty (short full-replace window, then prorated)
- Foam-over-air construction — none of them feel like traditional innersprings or hybrids
What all four are missing
- Real coil support — every model rides on air, not steel
- Traditional pillowtop bounce
- Strong edge support (foam encasements compress under sitting weight)
- An affiliate or price-match program — Sleep Number sells direct at fixed pricing
Frequently asked questions
Where did the c2, p5, i8, i10 models go? Discontinued in the late-2025 rebrand. The current lineup is ComfortMode / ComfortNext / ClimateCool / Climate360.
Is a Sleep Number mattress worth it? If dual firmness or active climate is your specific problem, yes — nobody else solves those problems as well. For general “I want a great mattress,” no — a premium hybrid at the same price outperforms on feel, edge support, and longevity.
Can I try Sleep Number at Yawnder? No — we don’t carry the brand. Our San Diego showroom stocks a premium pillowtop and hybrid lineup so you can compare traditional mattress feel against what Sleep Number is doing.
What’s the return policy really like? 100 nights sounds generous, but the $199 restocking fee and the fact that you have to disassemble and ship it back at your expense means real returns are painful. Try in-store first.
Are the sales real? Sleep Number runs near-constant promotional pricing. The MSRPs are inflated; the “sale” price is basically the price. Wait for a holiday for the deepest cut.
Bottom line
Sleep Number’s 2026 lineup is finally simple: four beds, each with a clear job. Buy the tier that matches your actual sleep problem — don’t over-buy for features you won’t use, and don’t under-buy on cooling if you actually sleep hot.
