Two sleepers. One mattress. Zero compromise.

Each side has its own air chamber and its own remote. Drag to feel how firmness changes — from a plush 1 to a firm 50 — independently on each side.

Engineered to disappear

No external pumps. No hoses on the floor.

The air system is built directly into the mattress rail — not a noisy box tucked under the bed. It stays quiet, hidden and out of your way, so the technology fades into the background and the comfort is all you notice.

  • Pump sealed inside the rail — nothing to trip over or hide
  • Whisper-quiet adjustments, even in the middle of the night
  • No tangled hoses that leak or wear out over time
No external pumps. No hoses on the floor.
50 settings, per side

Dial in the exact support your body wants.

Fifty comfort settings let you fine-tune from feather-soft to extra-firm on a 1–50 scale. As your body changes — pregnancy, recovery, or simply a new preference — your mattress changes with it, no new bed required.

  • Independent left and right chambers with two remotes
  • Reduced pressure points for hips, shoulders and lower back
  • Even weight distribution for true spinal alignment

The one question we get asked

What's the difference between the 10", 12" and 14"?

Same 50-setting air system in all three. The difference is the pillow top.

Why people switch

Benefits you'll actually feel

A mattress that adjusts to you tends to fix the problems a fixed mattress can't.

Ease back & joint pain

Tune support to hold your spine in alignment and wake without the aches a too-soft or too-firm bed leaves behind.

Deeper, calmer sleep

When the surface truly cradles your body you toss and turn less and stay in restorative sleep longer.

Adapts to your life

Pregnancy, surgery recovery, aging, or a change of heart — adjust anytime instead of buying a new bed.

Zero motion transfer

Independent air chambers mean a restless partner stays on their side of the bed — you won't feel a thing.

Cool all night

A breathable pillow top and airflow-designed comfort layers pull heat away instead of trapping it.

Built for the long run

One bed that changes with you, backed by a 25-year warranty — instead of replacing a mattress every few years.

Customer Reviews

Overall rating: 5.0 / 5 from 1 reviews.

Like the seller, really helped me out quickly with a mistake I made. Just set up my "split" king yesterday. Everything worked and nothing was broken or missing. Adjustable base is extremely heavy but I'm not sure of its longevity due to no center supports. You will not find another setup like this for this price. I replaced a sleep number with this bed, if I was to buy the same sleep number it would be about 6K..frickin ridiculous for what it is. Shipping was as told by seller.
