Quick Answer: The Saatva Adjustable Base Plus ($1,360–$1,599 queen) is the best zero gravity adjustable bed overall — its pillow-tilt feature and dedicated lumbar zone let you fine-tune the position instead of locking into one fixed recline. The Sven & Son Classic Series (roughly $1,000 queen) gives the widest one-touch articulation range at 0–75° head and 0–45° foot, and the Purple Premium Smart Base (about $995–$1,195 queen) is the only pick here with app-based custom-angle control beyond its built-in preset. The “zero gravity” name comes from NASA’s Skylab-era research into neutral body posture — the position the human body naturally settles into when weightless — and today’s adjustable bases approximate it with the legs raised above heart level and the torso gently reclined.
Every adjustable base sold today advertises a zero-gravity preset, but the position you actually land in — and how easily you can adjust it — varies more than the marketing copy suggests. Some bases give you one fixed angle at the press of a button; others let you fine-tune the recline, add lumbar support, or dial in a custom angle from a phone app. We focused these picks on articulation range, preset precision, and how easy each base makes it to actually find and hold the position, rather than just whether “Zero G” appears on the remote.

1. Saatva Adjustable Base Plus — Best Overall
Saatva Adjustable Base Plus
- One-touch zero-gravity preset, plus a pillow-tilt feature and dedicated lumbar-support zone most competitors don't offer — see our full Saatva Adjustable Base Plus review.
- Fine head/foot articulation lets you nudge away from the default preset angle instead of accepting one fixed position.
- Free white-glove delivery and setup included.
The Saatva earns the overall pick because it doesn’t stop at a single preset button. The pillow-tilt feature adjusts the head angle independently of the rest of the recline, and the lumbar zone fills the gap under the lower back the way a physical therapist might target with a support pillow — useful if the stock zero-gravity angle doesn’t quite land right for your height or where you carry tension. It’s also our top pick in the best adjustable bed for back pain roundup for the same reason.

2. Sven & Son Classic Series — Widest Articulation
Sven & Son Classic Series
- Head articulates 0–75° and the foot 0–45°, the widest combined range of any base in this roundup.
- One-touch zero-gravity preset alongside anti-snore, flat, and two programmable memory positions.
- Wireless remote and quiet dual motors, so finding the position doesn't wake a partner.
A wider articulation range matters for zero gravity specifically because the “correct” angle isn’t universal — it depends on your height and where the base’s pivot points line up with your hips and knees. At 75° of head lift and 45° at the foot, the Sven & Son gives you more room to adjust away from the factory preset than most bases at this price, and it does it for roughly $360-$600 less than the Saatva. It’s also our overall top pick in the best adjustable bed roundup.
3. Purple Premium Smart Base — Best Custom Control
Purple Premium Smart Base
- Smartphone app control (iOS/Android) lets you dial in a custom recline angle beyond the built-in Zero-G preset, not just pick from fixed positions.
- Zero-clearance design works on platform and slatted frames without legs, alongside the standard four presets (Zero-G, lounge, anti-snore, flat).
- 750-lb weight capacity and a genuinely quiet lift motor.
Every base here has a one-touch zero-gravity button, but the Purple is the only one where the app lets you nudge past that preset to a fully custom angle and save it — useful if the stock position raises your legs a bit too high or not quite enough. It’s the direct successor to Purple’s discontinued Ascent base; see our full Purple Premium Smart Base review for what carried over and what changed, including that it still skips massage entirely.
4. Lucid L300 — Best Budget
Lucid L300
- Head articulates 0–70° and the foot 0–45°, close to the Sven & Son's range at a lower price.
- A dedicated one-touch Zero Gravity preset appears on newer L300 listings, but older/other listings only offer manual head-and-foot adjustment with a savable memory position — confirm the specific listing before buying if a one-touch preset is a must-have.
- USB charging ports and a wireless remote with a one-touch flat button.
The L300 proves you don’t need a four-figure base to get most of the way to zero gravity — 70° of head lift is only 5° short of the Sven & Son at roughly $200 less. The one catch is preset consistency: Lucid has updated this model over time, so whether “Zero Gravity” appears as a labeled one-touch button depends on the exact version you receive. Either way, you can manually raise the legs and recline the torso and save it as a memory position, so the position itself is always reachable even without the dedicated label.
What to look for in a zero gravity adjustable base
- Articulation range: Wider head and foot ranges (like the Sven & Son’s 0–75°/0–45°) give you more room to find the angle that actually works for your height, rather than accepting one fixed factory position.
- Fine-tuning beyond the preset: A pillow-tilt feature (Saatva) or app-based custom angle (Purple) lets you adjust away from the default preset instead of settling for it.
- Preset labeling vs. manual adjustment: Not every listing of the same model includes a labeled one-touch Zero Gravity button — check the Lucid L300’s example above. The position is usually reachable manually either way, via head/foot buttons and a memory-save function.
- What it’s actually for: Elevating the legs above the heart helps with swelling and circulation; reclining the torso reduces how easily stomach acid travels back up the esophagus. If back pain specifically is the goal, see our best adjustable bed for back pain picks, which add lumbar support on top of the zero-gravity recline. If sciatic nerve pain is the specific issue, our best adjustable bed for sciatica picks focus on independent leg-elevation control rather than a single fixed preset.
- Mattress compatibility: The position only works if your mattress flexes with the base. Memory foam, latex, and most pocketed-coil hybrids handle it; older innerspring-and-box-spring setups don’t — see our adjustable bed mattress compatibility guide.
The “zero gravity” name isn’t marketing fluff — it traces back to real NASA research on how the body settles when weightless, first measured aboard Skylab and formalized as neutral body posture in the agency’s NASA Standard 3000 documentation. Adjustable-bed makers approximate that same posture on the ground, and while the exact angle varies slightly by brand, the underlying idea (legs above the heart, torso gently reclined) is consistent across every pick in this roundup.
The bottom line
The Saatva Adjustable Base Plus is the best zero gravity adjustable bed overall, thanks to pillow-tilt and lumbar-zone fine-tuning most bases don’t offer. Want the widest one-touch articulation range for less money? The Sven & Son Classic Series. Want to dial in a fully custom angle from your phone? The Purple Premium Smart Base. On a budget, the Lucid L300 gets you 70° of head lift for around $799 — just confirm your specific listing includes the labeled preset if that matters to you.
