Need Help Deciding?
For most sleepers, we recommend the Sleep Number 360 i8 Smart Bed over the Tempur-Pedic TEMPUR-ProAdapt. It scores higher in cooling, price-to-value and offers strong overall value at $2,399 (vs $3,399). The Tempur-Pedic TEMPUR-ProAdapt is the better choice only if you have a strong preference for that brand's specific feel or design.
Sleep Number 360 i8 Smart Bed vs Tempur-Pedic TEMPUR-ProAdapt: What Actually Differs
The Sleep Number 360 i8 Smart Bed is a smart bed build, while the Tempur-Pedic TEMPUR-ProAdapt is a memory foam — that single difference drives most of the cooling, motion, and feel decisions below. Profile-wise they're almost identical — the Sleep Number 360 i8 Smart Bed measures 12" and the Tempur-Pedic TEMPUR-ProAdapt measures 12", so neither will dictate your sheet depth or bed-frame compatibility. The Tempur-Pedic TEMPUR-ProAdapt is the firmer of the two at 6/10 (medium-firm), and the Sleep Number 360 i8 Smart Bed sits at 5/10 (medium) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in motion isolation: the Tempur-Pedic TEMPUR-ProAdapt rates noticeably higher than the Sleep Number 360 i8 Smart Bed, which is the deciding factor if that dimension is high on your list. On a Queen, the Sleep Number 360 i8 Smart Bed runs $2,399 versus $3,399 for the Tempur-Pedic TEMPUR-ProAdapt — roughly $1,000 (29%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.
Which Is Better For Your Sleep Style?
Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.
Firmness of 6/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 5/10).
Firmer at 6/10 vs 5/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Cooling rating not available for one or both mattresses — spec not available.
Durability and edge-support ratings are equivalent — either holds up.
Softer at 5/10 vs 6/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
