The short answer

Helix Adjustable Base and Sleep Number i10 Smart Bed score essentially the same (4.4 vs 4.4). Pick the one whose trade-offs match your priorities — the strengths and watch-outs below are where they actually differ.

Ranked #3 in Best Adjustable Beds

Helix Adjustable Base

4.4

3 sources$999as of Jun 7

The Helix Adjustable Base hits the sweet spot for buyers who want premium hardware features (under-bed lighting, USB charging, dual-zone massage) without crossing the $1,500 line. Its 20-year warranty runs unusually long for the mid-tier, and Mattress Clarity scored it 4.6/5. Dropping the wall-hugger function is the main concession to price.

Strengths

— Under-bed lighting is rare at this price point
— USB-A and USB-C ports on each side of the frame
— Two-zone massage (head and foot) with three intensity levels

Watch-outs

— No wall-hugger function — frame moves away from the wall on incline
— Single-motor design is audible at higher speeds compared to dual-motor rivals
— No smart app, snore detection, or sleep tracking

Ranked #4 in Best Adjustable Beds

Sleep Number i10 Smart Bed

4.4

2 sourcesall derived$5,199as of Jun 7

The i10 heads Sleep Number's Innovation Series and is built to pair with the FlexFit smart adjustable base for the brand's most premium smart-bed setup. Nothing else at this tier matches its per-side air-chamber adjustability or continuous biometric sleep tracking. The price, though, puts it in a different conversation than every other product on this list, and the thick comfort layer retains heat, which hot sleepers should weigh.

Strengths

— DualAir adjustability lets each side dial firmness from 0 to 100 independently
— SleepIQ tracks heart rate, breathing rate, and movement with no wearable required
— Responsive Air automatically adjusts firmness during the night based on movement

Watch-outs

— $5,399+ for the Queen mattress; FlexFit base adds substantially more
— 5-7 inches of comfort foam over air chambers traps heat compared to coil hybrids
— Warranty escalates fast — full coverage only in year one, 85% pro-rated by year 15

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

Helix Adjustable Base

Beats the Nectar Premier Adjustable Base on warranty length (20 years vs 3) and the Lucid L300 on feature density (massage and under-bed lighting). Sits below the Saatva Adjustable Base Plus on wall-hugger performance and number of massage zones, but at roughly $600 less.

Sleep Number i10 Smart Bed

The Sleep Number i10 is the highest-spend pick on this list by a wide margin — multiple times the cost of the Tempur-Pedic Ergo Smart Base or the Saatva Adjustable Base Plus. It earns the slot for buyers who specifically want per-side adjustable firmness and SleepIQ biometrics, but the Helix Adjustable Base, Nectar Premier Adjustable Base, and Lucid L300 are all in a different value conversation entirely.
