Up and across
Rollers travel the length of the track and side to side across your back. Pressure is fixed — whatever the chair gives you is what you get.
Rollers travel the length of the track and side to side across your back. Pressure is fixed — whatever the chair gives you is what you get.
Rollers push outward from the track, so you set how far into the muscle the pressure reaches. You control how hard.
Speed and pressure change over time. The roller lingers, quickens, eases off. That variation is the whole difference — it reads as a pair of hands rather than a motor.
3D controls how hard. 4D controls how hard, and when.
Not for everyone — and we would rather say so here than have you find out after delivery. 4D adds real cost. Whether it earns that cost depends entirely on how you plan to use the chair.
All four run 4D rollers. What separates them is track length, heat coverage, colour range and how much intelligence sits on top.

If 4D adds rhythm to depth, 5D adds adaptive intent. The chair registers how your body responds mid-session and reshapes the programme as it runs, instead of executing one you chose at the start.
Entry to the range. The Niyak, with health sensors and AI voice control.
Rayan and Ayla. Added comfort features and softer finishes.
The Auren. Extended track, fullest heat coverage, thirteen colours.
All four are available through Affirm at 0% APR for eligible buyers over 24 to 36 months — on the Niyak that lands near $276 a month across 36 months, with no interest added. Every chair carries a 3-year warranty and free return shipping within 90 days.
For regular use, yes. The advantage over 3D is not more force but more variation — the roller changes speed and pressure through a session, so twenty minutes does not feel like one motion repeated. If you use a chair occasionally and prefer steady pressure, a 3D chair will serve you just as well.
A roller mechanism that moves in three physical directions — up, across, and outward from the track — and also varies its speed and rhythm over time. The first three dimensions are geometry. The fourth is timing.
5D adds adaptive intent on top of 4D. The chair reads how your body responds during the session and reshapes the programme as it runs, rather than executing a fixed one. Our Weltron uses a 5D system.
Across the market, 4D chairs start around $4,000 and climb past $20,000. Ours run from $9,950 for the Niyak to $14,799 for the Auren, with the 5D Weltron above them at $16,799.
If you sit in the chair most days, or you are managing a specific complaint, or more than one person uses it, 4D earns the difference. For light occasional use, 3D is enough — and we would rather you kept the money.
All four chairs in our 4D range do. The Weltron sits above them on a 5D system.
