Quick Answer: If your base is a Leggett & Platt-powered model — including many private-label bases sold under other brand names — an OEM Leggett & Platt replacement actuator matched to your series (Basis, S-Cape, or T-120) is the safest fix. If you can’t identify the motor brand at all, the Okin universal actuator motor is built to work with several common hand-control families (OKIN, DEWERT, LIMOSS) rather than one proprietary system. And if your base uses the now-discontinued Okimat 2 motor, the Richmat HJA1/HJA3 DualDrive is the direct successor part sold specifically as its replacement.
A dead adjustable base is rarely a reason to replace the whole thing. The head and foot sections each move on a separate linear actuator — a small electric motor paired with a telescoping rod — and these parts are designed to be swapped when they wear out, the same way you’d replace a garage-door opener’s motor rather than the whole door. The harder part isn’t installation; it’s identifying which motor is actually inside your base, since the brand printed on the mattress packaging often isn’t the company that made the motor.

1. Leggett & Platt OEM Replacement Actuator — Best Overall
Leggett & Platt Adjustable Bed Replacement Actuator
- Leggett & Platt is the largest adjustable-base motor manufacturer in North America, supplying private-label bases to a long list of mattress brands — so a base with no "Leggett & Platt" branding anywhere on the headboard may still run one of their actuators underneath.
- Sold as separate head and foot actuator listings matched to specific series (Basis, Lifestyles S-Cape, T-120, and older Series 100 II bases), since the mounting bracket, stroke length, and connector plug differ between generations.
- Ordering the exact series match, not a generic-looking lookalike, is what determines whether the plug actually fits the existing wire harness without an adapter.

Before ordering, check the sticker on the underside of the base or on the control box itself for a series name — it’s usually a short code like “S-Cape” or “T120” rather than the mattress-company name printed on the outside of the base.
2. Okin Universal Actuator Motor — Best If Your Base Is Unidentified
Okin Actuator Motor for Adjustable Beds
- Okin is one of the largest independent motor manufacturers supplying adjustable beds and hospital beds, and its actuators are built to pair with several common hand-control families rather than one proprietary brand ecosystem.
- A practical starting point when the base has no visible brand sticker, was bought secondhand, or came bundled with a mattress under a name that isn't a motor manufacturer at all.
- Match the stroke length (the actuator's travel distance, typically listed in millimeters) and the connector plug shape against your old motor before ordering — Okin sells multiple stroke-length variants, and a shorter or longer stroke than the original won't seat correctly in the base's frame.
If your existing remote uses the OKIN, DEWERT, or LIMOSS naming on its pairing screen or manual, that’s a strong sign an Okin actuator will match — those three brands share compatible hand-control protocols.
3. Richmat HJA1/HJA3 DualDrive Motor — Best Okimat 2 Replacement
Richmat HJA1/HJA3 DualDrive Motor
- The original Okimat 2 motor has been discontinued, and Richmat's HJA1 (standard, no massage) and HJA3 (dual-drive, premium) motors are sold specifically as its replacement by parts suppliers like Genesis Warranty Solutions.
- Because it's a cross-brand successor rather than an exact OEM reissue, confirm your base's mounting bracket spacing and connector type against the listing photos before ordering — "successor part" means functionally compatible, not necessarily a drop-in physical match on every base.
- Worth checking if your base is old enough that the original manufacturer no longer stocks parts for it at all, which is common once a motor generation is a decade or more old.
If your base predates most current adjustable-bed brands and the original manufacturer no longer sells parts for it, a successor motor like this is often the only path other than replacing the entire base.
How to identify which motor you actually need
- Check the control box, not the headboard. Many private-label bases run a Leggett & Platt or Okin motor underneath a mattress-company name printed on the outside — the motor brand is the one that matters for parts matching.
- Count your actuators before ordering. Most bases use two (head and foot); some add a third for massage. Order the specific one that’s failed rather than assuming a single part covers the whole base.
- Match stroke length and plug shape, not just brand. Two motors from the same manufacturer can use different stroke lengths and connector shapes across product generations — compare against your old part’s physical dimensions, not just its brand name.
- Rule out the remote first. If the base doesn’t respond to any input at all — not the remote, not a manual control-box button — that points to the motor or power supply rather than the handset; if only the remote fails to trigger movement, see our replacement remote guide instead.
The bottom line
Identify the motor brand behind your base before ordering anything — the Leggett & Platt OEM Replacement Actuator, matched to your exact series, is the most reliable fix for the largest share of bases on the market. If the motor brand is a genuine mystery, the Okin Universal Actuator Motor covers several of the most common hand-control families without requiring an exact OEM part number. And if your base runs the discontinued Okimat 2 motor, the Richmat HJA1/HJA3 DualDrive is the direct successor part built to replace it.
