by The Amerisleep AS3 paired with the Amerisleep Adjustable Bed is the best adjustable bed bundle in 2026 for most sleepers: medium feel, 5-zone HIVE support, and a base that delivers zero-gravity and head-elevation presets in one purchase. If you need split-king independent adjustment for two sleepers, the AS3 Split King bundle is the natural choice. The only reason to look elsewhere is if you want luxury hotel-grade coil support, in which case a different brand fits better, but no Amerisleep alternative comes close on value, trial length, or foam quality.
Amerisleep AS3
9.3/10
- HIVE 5-zone layer firms under the lumbar and hips for precise spinal support in any adjustable position
- Plant-based Bio-Pur foam flexes smoothly with head and foot articulation without cracking or bunching
- Medium 5/10 feel works for back, side, and combo sleepers, including zero-gravity recline
- CertiPUR-US certified, made in the USA, free shipping
- 20-year warranty, 100-night risk-free trial with free returns
- All-foam construction means softer edge support than a coil hybrid
- Sleepers over 230 lb may find the AS5 Hybrid a better long-term fit on an adjustable base
The AS3 is purpose-built for adjustable base pairing. Its Bio-Pur foam bends with head and foot articulation without resistance, and the HIVE zoning keeps lumbar support intact whether you are flat or in zero-gravity. At $1,049 for a queen, it is the most cost-effective path to a full adjustable bundle with Amerisleep quality behind it.
Why the AS3 works on an adjustable base
Not every mattress pairs well with an adjustable base. Innerspring models with interconnected coils can creak or resist head-and-foot articulation. Dense memory foam can take longer to return to position after angle changes. The AS3 Bio-Pur foam is specifically designed to flex: it is open-cell, partially plant-based, and lighter than traditional memory foam, which means it articulates smoothly and does not fight the motor.
The HIVE 5-zone layer below the Bio-Pur comfort foam does the structural work. The hexagonal cutouts are denser under the lumbar (zone 3 of 5) and lighter under the shoulders and feet, so when you raise the head section to 30 or 45 degrees, the lumbar zone still provides firmer resistance. This matters because most adjustable position benefits, including zero-gravity and the head-elevation incline, only work if the mattress keeps the spine in a neutral arc. A mattress that goes uniformly soft throughout undermines the positioning entirely.
Amerisleep explicitly recommends the AS3 on their adjustable bed product pages, and it is the most-purchased pairing in their lineup. That means the return rate for this combination is low enough that they actively push it as the default recommendation.
Amerisleep Adjustable Bed: specs and model differences
Amerisleep offers two adjustable base models in 2026. Understanding the difference prevents ordering the wrong tier.
| Feature | Amerisleep Adjustable Bed | Amerisleep Adjustable Bed+ |
|---|---|---|
| Head elevation | Up to 60 degrees | Up to 60 degrees |
| Foot elevation | Up to 40 degrees | Up to 35 to 40 degrees |
| Zero-gravity preset | Yes, one-touch | Yes, one-touch |
| Head-elevation anti-snore preset | Yes | Yes |
| Wireless remote | Backlit remote included | Remote plus app plus Alexa/Google |
| Massage | No | Yes, built-in |
| USB ports | No | Yes |
| Under-bed lighting | No | Yes |
| Weight capacity | ~700 lb (sleeper plus mattress) | ~700 lb (sleeper plus mattress) |
| Warranty | 10 years (tiered) | 10 years (tiered) |
| Split King / Split Cal King | Available | Split King available |
| Starting price (queen) | ~$1,000 to $1,100 | ~$1,800+ |
The standard Amerisleep Adjustable Bed is the right choice for most buyers. It covers the two features that actually affect sleep quality, zero-gravity and head-elevation incline, without paying for massage or USB ports that most people stop using within a year. The Bed+ is worth considering only if app control or the built-in massage are priorities.
Both models carry a 10-year tiered warranty: full parts and labor in year 1, mechanical and electrical in year 2, and prorated metal frame replacement from years 3 through 10.
Zero-gravity: what it does and why it matters
Zero-gravity position places the head slightly elevated and the knees slightly raised above the heart, approximating the neutral body position NASA developed for astronauts during launch. In practice the head sits at roughly 20 to 30 degrees and the feet at around 15 to 20 degrees, so the hips form a gentle V shape.
Three things happen in this position that do not happen flat:
- Lumbar disc pressure drops. Flat on your back, disc pressure at L4-L5 runs around 25 psi. A slight knee raise pulls the pelvis posterior and opens the disc spaces, reducing that load measurably.
- Lower-limb circulation improves. Elevating the feet above heart level reduces venous pooling in the legs, which is why zero-gravity is frequently recommended for people with edema or restless legs.
- Acid reflux risk decreases. Head elevation of 20 degrees or more physically raises the esophagus above the stomach, which reduces the chance of nighttime reflux without requiring a full bed wedge.
The AS3 medium feel handles this well. On a very firm mattress, zero-gravity puts too much pressure on the sacrum. On a very soft mattress, the lumbar collapses into the foam during incline. The AS3 medium 5/10 and HIVE zoning hit the middle ground that makes zero-gravity positioning physically effective.
Head-elevation preset and snoring
Both Amerisleep base models include a head-elevation preset that raises the head section to reduce airway obstruction during sleep. This works by tilting the upper body so the tongue and soft palate are less likely to fall back and narrow the airway. It is not a treatment for sleep apnea, but it is a meaningful benefit for positional snoring and mild obstruction.
The preset engages with one button on the wireless remote. It is marketed as a head-elevation preset and achieves the same outcome as what competitors label an anti-snore button. The AS3 foam compresses cleanly at this angle without pushing back against the articulation.
Bundle pricing and Split King options
Amerisleep sells the AS3 and adjustable base as a bundle with bundled savings. As of mid-2026, bundle pricing reflects roughly 25 to 30 percent savings versus buying separately, with periodic promotions bringing the queen bundle to approximately $1,679. Split King configurations, which use two Twin XL AS3 mattresses on two independent adjustable bases, run higher because each sleeper gets a separate motor and remote.
| Configuration | What you get | Approx. price range (2026) |
|---|---|---|
| Queen AS3 + Adjustable Bed | 1 mattress + 1 base, shared controls | ~$1,679 to $2,100 with promo |
| Split King AS3 + Adjustable Bed | 2x Twin XL AS3 + 2x adjustable bases | ~$4,000 to $4,300 with promo |
| Split King AS3 + Adjustable Bed+ | 2x Twin XL AS3 + 2x Bed+ bases | ~$4,600+ with promo |
Split King is the right choice when two sleepers have different position preferences. Each base adjusts independently, so one person can sleep flat while the other uses zero-gravity. The AS3 in Split King uses two separate Twin XL mattresses, meaning there is a small gap at the center that most couples find negligible. A Split King mattress pad or a king-size bed bridge can close that gap if needed.

How to order the bundle
Amerisleep ships the AS3 and adjustable base separately via FedEx to the continental US. Shipping is free on both. Setup is designed for two people because of the base weight, though many customers complete it solo. The steps:
- Select the bundle on amerisleep.com and choose queen, king, Split King, or Cal King.
- Choose between the standard Adjustable Bed or Adjustable Bed+.
- Apply any active promo code at checkout. Amerisleep typically runs seasonal discounts of 20 to 30 percent.
- Delivery arrives in 5 to 10 business days. The base ships flat-packed and requires basic assembly of legs and frame sides.
- The 100-night trial starts on the mattress delivery date. The base carries a separate 10-year warranty.
Financing through Klarna is available at 0% APR, with Pay-in-4 for orders under $1,000 or installment plans for larger bundles. The Split King bundle typically qualifies for the 12- or 18-month financing option.
Warranty and trial
The AS3 mattress carries Amerisleep 20-year warranty: years 1 through 10 cover defect repair or replacement at no cost, and years 11 through 20 provide a replacement mattress at 50 percent of the current purchase price. The warranty covers manufacturing defects and sagging greater than 1.5 inches. It does not cover normal wear or damage from an inadequate foundation, but Amerisleep own adjustable base qualifies as a proper foundation, so using the two together keeps the warranty intact.
The 100-night trial is risk-free: if the AS3 is not working at any point in the first 100 nights, Amerisleep arranges free pickup and issues a full refund. The adjustable base is not covered under the mattress trial, but the 10-year warranty on the base covers mechanical and electrical failure separately.
The Amerisleep AS3 plus Adjustable Bed bundle is the most complete, verifiable adjustable sleep setup at this price point. Bio-Pur foam flexes with articulation, HIVE zoning keeps lumbar support intact in zero-gravity, and the base delivers the two presets that matter, zero-gravity and head elevation, without overpaying for extras. Use the 100-night trial to confirm the fit.
Frequently asked questions
Does the Amerisleep AS3 work with any adjustable base, or only Amerisleep bases?
The AS3 is compatible with most standard adjustable bases from any brand. Amerisleep own base is recommended because the two are tested and sold together, and using the Amerisleep base keeps the mattress warranty straightforward. A third-party base that is not flat and solid can void the warranty if it causes damage.
What is the difference between the Amerisleep Adjustable Bed and Adjustable Bed+?
The standard Adjustable Bed includes zero-gravity and head-elevation presets, a wireless backlit remote, and a 10-year warranty. The Adjustable Bed+ adds massage, USB ports, under-bed lighting, and app plus voice control via Alexa and Google. Both have similar head and foot elevation ranges and the same weight capacity. If massage and smart-home integration are not priorities, the standard base is the better value.
Is Split King worth the extra cost?
Split King is worth it specifically when two sleepers have different position needs, where one wants zero-gravity and the other prefers flat. Each base operates independently on a Split King. If both sleepers are comfortable with the same position, a standard king bundle is simpler and significantly cheaper.
Does zero-gravity actually help with back pain?
Positioning evidence is well established: elevating the knees reduces lumbar disc pressure compared to sleeping flat, and head elevation above 20 degrees can reduce acid reflux. These are mechanical effects, not medical treatments. For chronic back pain, the combination of a medium-firm zoned mattress and zero-gravity positioning addresses the two most common positional contributors, disc pressure and lumbar sag, simultaneously.
Can I use the Amerisleep adjustable base with my current mattress?
Possibly, if your current mattress is all-foam or a hybrid with independently pocketed coils and no innerspring borders. Traditional innerspring mattresses with connected coils typically cannot flex on an adjustable base and may be damaged. Amerisleep base works best with their own foam mattresses, and the AS3 is the recommended pairing.
