5 Smart Beds That Will Upgrade Your Sleep in 2025

If you want the most integrated climate control we've tried, the Sleep Number Climate360 pairs active dual-zone cooling and warming with independently adjustable firmness on each side. During our review, built-in sleep tracking was convenient, but the SleepIQ app can be glitchy and the climate modules may be audible in quiet bedrooms. Total cost is steep, especially once setup and optional remote fees are added. Compared with Eight Sleep's Pod 5, you get firmness adjustability - but at a far higher price.

Among Sleep Number's softer-feeling models, the i8 stands out for adjustable-air comfort with strong motion isolation that kept partner disturbance minimal in our testing. Larger sizes offer dual-sided firmness control, and built-in sleep tracking reads heart and respiratory rates for nightly insights. Watch out for heat buildup - temperature regulation can lag without extra cooling - and some users report inconsistent sleep-tracking accuracy. Also note the adjustable base is typically non-refundable, which adds risk if you're still deciding on your setup.

Eight Sleep's Pod 5 Core impressed us with dual-zone temperature control and an Autopilot mode that learns your patterns to optimize cooling or warming through the night. During our review, the biometric tracking for heart and breathing added useful insights, though it doesn't adjust firmness like an air-chamber bed. Be aware of the high upfront cost plus ongoing subscription, and reports of pad leaks and app regressions. It still delivers climate tech at a fraction of the Sleep Number Climate360's price.

For hot sleepers who want premium foam, the TEMPUR-LuxeBreeze Firm excels at keeping heat at bay with an effective multi-layer cooling system. During our review, it flexed smoothly on adjustable bases without fabric bunching, which makes it great for split configurations. The catch is the sky-high price and heavy build, which can complicate delivery, setup, and registration. Some owners also report firmness loss or sagging over time, so we'd buy from a retailer with strong service support.

Sleep Number's P5 is a solid entry into adjustable-air comfort, letting each partner set a unique firmness while SleepIQ tracks nightly trends in the app. In our testing, the 100-night trial and 15-year limited warranty provided confidence, but the comfort foam can feel thin for dedicated side sleepers. We also noticed some off-gassing initially, and couples who cuddle in the middle may feel a center indentation from the dual chambers. If you want more cushioning, consider stepping up within Sleep Number's lineup.

Purple's Premium Plus Smart Base brings serious comfort features, including targeted lumbar support, dual-zone massage with multiple intensities, and one-touch presets like Zero-Gravity and Anti-Snore via app or remote. In our testing, those presets made nightly adjustments effortless. The trade-offs are price and bulk - assembly can be a chore, and it lacks meaningful wall-hugging, so your mattress may shift forward when elevated. If you prioritize massage and lumbar support over compact design, this base is a crowd-pleaser.
