5 Best King Adjustable Bed Frames of 2026 — Maximum Space, Maximum Comfort
A king adjustable bed gives you 76 inches of width — enough room for two adults to sleep, stretch, and adjust without crowding each other. Whether you choose a standard king (one base, both sides move together) or a split king (two bases, independent control), here are the best options we tested.

Standard King vs. Split King: Which Should You Choose?
The first decision with a king adjustable bed is whether to go standard or split. This affects everything — price, mattress choice, sheet selection, and how you and your partner sleep.
| Feature | Standard King | Split King |
|---|---|---|
| Control | Both sides move together | Each side independent |
| Bases Needed | 1 king base | 2 Twin XL bases |
| Mattresses | 1 king mattress | 2 Twin XL mattresses |
| Center Gap | None | Small gap (fixable with filler) |
| Base Cost | $427-$1,599 | $854-$3,198 (2x) |
| Best For | Same-position couples, budget | Different-preference couples |
Our recommendation: If you and your partner always want the same bed position, a standard king saves significantly. If either of you reads, watches TV, or has different elevation needs (snoring, acid reflux, back pain), a split king is worth the premium.
King Adjustable Bed Dimensions & Specs
A king adjustable bed is the largest standard size available (not counting California King, which is 72" x 84" — narrower but longer). It offers 16 more inches of width compared to a queen (60"), giving each partner about 38 inches of personal space — the same width as a Twin XL.
Weight is a real consideration for king bases. At 140-200 lbs for the base alone (plus 80-120 lbs for a king mattress), the total setup can weigh 220-320 lbs. Most premium brands offer white-glove delivery for king sizes, and we recommend it unless you have help available.
Best King Adjustable Bed Frames — Full Reviews
Nectar Premier Adjustable Base
Nectar
$749
Starting price
- + 3 massage settings + memory position presets
- + 4 USB ports for bedside charging
- + Near-silent operation at 47 dB
- - Higher price than Amazon-native brands
- - Incompatible with some headboard styles
King-Size Performance
Nectar brings mattress-brand credibility to the king adjustable base category. The Premier Base pairs three massage settings with memory position presets and four USB ports — two on each side, so both sleepers get bedside charging access across the full 76" width. At 47 dB, it's one of the quietest king bases we tested, which matters more when two people share a bed and nighttime adjustments could wake a light sleeper. Priced at $749, it sits in the sweet spot between budget kings and premium options, and Nectar's dedicated customer support gives you a safety net that Amazon-only brands can't match.
Blissful Nights e4 Adjustable Bed
Blissful Nights
$539
Starting price
- + Massage + anti-snore + zero gravity presets
- + Dual USB charging ports
- + Under-bed LED lighting
- - Less stable at extreme head angles
- - Remote buttons are small
King-Size Performance
The Blissful Nights e4 is the feature-packed upgrade from Amazon's most trusted adjustable bed brand. Available in both standard King and Split King, it gives couples the option to start with a single king base and upgrade to independent control later. Massage, anti-snore presets, dual USB ports, and under-bed LED lighting are all included at $539 — a price point that king-size competitors rarely match. With 1,660+ reviews at 4.6 stars, it's also available in Cal King if your room is narrower but longer (72" x 84").
Sven & Son Harmony Adjustable Bed Base
Sven & Son
$1,599
Starting price
- + 1,060+ reviews at 4.5 stars — proven reliability
- + Full-body massage + ambient lighting
- + Memory position presets
- - Premium pricing at ~$1,600
- - Primarily Amazon-only brand
King-Size Performance
The Sven & Son Harmony is built for couples who want a premium king experience with every comfort feature included. Full-body massage, ambient lighting, and memory presets come standard, and the available Split King configuration lets each partner independently adjust their side. At $1,599, the king price is steep, but 1,060+ reviews confirm the build quality and motor reliability hold up over years of nightly use. For a 76" x 80" king bed in a 12' x 14' or larger bedroom, the Harmony delivers a luxury feel without the $2,000+ price tags of Tempur-Pedic or Sleep Number.
ESHINE King Adjustable Bed Frame
ESHINE
$784
Starting price
- + German-engineered OKIN motor — industry gold standard
- + Full-body massage with 3 levels and 3 modes
- + 19-button wireless remote with backlight
- - 19-button remote has a learning curve
- - Higher price point for king size
King-Size Performance
The ESHINE earns our top king pick thanks to its German-engineered OKIN motor — the same brand used in hospital-grade adjustable beds — which handles the extra weight of a 76" x 80" king mattress without strain. The 19-button backlit remote takes a day to learn but gives you precise control over head, foot, and three-level full-body massage from either side of the bed. At $784, it undercuts most name-brand king bases while delivering premium build quality backed by 1,410+ reviews and a 10-year warranty. If your room is 12' x 12' or larger and you want a single king base that both partners control together, the ESHINE is the strongest all-around value.
Mixcous King Adjustable Bed Frame
Mixcous
$427
Starting price
- + Most affordable king-size adjustable base
- + Whisper-quiet motor operation
- + Zero gravity + anti-snore wireless remote
- - No massage or LED features
- - No Split King option
King-Size Performance
At $427, the Mixcous is the cheapest way to get a king-size adjustable base — period. It skips massage, LED lighting, and split functionality, but nails the fundamentals: whisper-quiet motor, zero gravity and anti-snore presets, and a no-tool installation that two people can finish in under 30 minutes. The king model fits the standard 76" x 80" mattress and works with any adjustable-compatible king memory foam, latex, or hybrid. If you're testing whether an adjustable king base fits your bedroom and sleep routine before committing to a $1,000+ model, the Mixcous is the lowest-risk entry point.

King Adjustable Bed Buying Guide
Weight Capacity Matters More at King Size
A king mattress weighs 80-120 lbs — significantly more than a queen (60-100 lbs). Combined with two adults, the total load on a king adjustable base can reach 500-700 lbs. Always check the manufacturer's weight capacity rating, which should account for the total load (mattress + sleepers). Most king bases are rated 750-850 lbs, but budget models may be lower.
Delivery and Setup Considerations
King adjustable bases are heavy (140-200 lbs) and bulky. Before ordering, verify:
- Doorway width: Your bedroom door should be at least 30" wide. Most king bases disassemble for delivery but check first.
- Stairs: If your bedroom is upstairs, confirm the stairway can accommodate the packaged base (usually shipped in a 40-50" box).
- White-glove delivery: Available from Nectar, Sven & Son, and most other brands for $100-$200. Highly recommended for king size.
- Old bed removal: Some brands include old bed haul-away with white-glove delivery.
King Adjustable Bed + Headboard
Many king adjustable bed owners want a headboard for that finished bedroom look. Here's what works:
- Wall-mounted headboards: Best option — they don't connect to the base at all, so nothing interferes with adjustment.
- Headboard-only frames: Bed frames without footboards that provide headboard attachment points while leaving the base free to move.
- Purpose-built frames: Frames designed specifically for adjustable bases — see our bed frames for adjustable beds guide.
Avoid: Traditional bed frames with footboards, center support bars, or cross-slats — all of these block the adjustable base from moving freely.
Sheets and Bedding for King Adjustable Beds
Standard king sheets can work on a single king adjustable base, but they tend to pop off when the head or foot elevates. Look for:
- Deep pocket sheets (16"+ pocket depth)
- Sheets with 360-degree elastic bands
- Stretchy knit or jersey materials
- Sheet straps or suspenders for extra security
See our guide on the best sheets for adjustable beds.
