Common questions about the Theramedic 4D LT
- How far does the roller path extend on the Theramedic 4D LT?
- SL-Track on the Theramedic 4D LT means the roller path traces your spine from cervical to lumbar and then curves under into the seat area, reaching the glutes. More ground covered than either an S- or L-Track alone — better for chronic lower back issues.
- What roller technology does the Theramedic 4D LT use?
- The Theramedic 4D LT features 4D rollers, which control both depth and the speed of each individual stroke independently. The result is a more rhythmic, human-like massage — the rollers can slow down and press deeper on tight spots, then speed up through less tense areas.
- Can the Theramedic 4D LT recline into a zero gravity position?
- Yes — the Theramedic 4D LT reclines into a zero gravity position, tilting your body so your legs rise above your heart. This reduces spinal compression and allows the rollers to work with gravity rather than against it, deepening the therapeutic effect.
- Is there built-in heat on the Theramedic 4D LT?
- Yes — the Theramedic 4D LT includes built-in heat, typically in the lumbar and sometimes calf sections. Heat loosens muscle tissue before and during the massage, making roller pressure more effective without needing to increase intensity.
- Does the Theramedic 4D LT scan your body automatically?
- The Theramedic 4D LT includes automatic body scanning. Before the massage begins, sensors measure your back and calibrate the roller path to your specific height and shoulder position.
- How much weight can the Theramedic 4D LT support?
- The Theramedic 4D LT is rated for a maximum user weight of 260 lbs (118 kg). Staying within this limit ensures both effective massage delivery and long-term mechanical reliability.
- Is the Theramedic 4D LT covered by a warranty?
- 5 years warranty on the Theramedic 4D LT. Coverage terms (parts vs. labour, in-home vs. depot service) can vary by retailer and region, so verify before buying.
- Which retailers carry the Theramedic 4D LT?
- You can find the Theramedic 4D LT at Direct. Prices and stock levels vary by retailer — our links point to current listings.
