MERACH MR-2440P1 vibration platform (pink)The MERACH MR-2440P1 vibration platform (pink) is a modern home training center that combines 200 W of power, 13 mm vibration amplitude, a wide 72 cm platform, a load capacity of up to 200 kg, and smart Auto On/Off and Bluetooth functions. The stable construction with a non-slip surface, clear LED display, shock absorption, and built-in speaker allow you to train effectively, safely, and comfortably—exactly how you like it. This compact device activates deep muscle groups and helps you achieve visible results faster without leaving home.Full control thanks to smart start and pauseThe MERACH MR-2440P1 is equipped with a built-in gravity sensor that automatically starts the device when you step on the platform and gently move side to side. When you step off the device, it goes into pause mode after 30 seconds and automatically turns off after 10 minutes. This is not only convenient, but also saves energy and ensures safe use.Customize your workout with three adjustable intensity levelsDifferent foot settings allow you to adjust the intensity of the vibrations. A narrower setting provides gentler vibrations ("Walking - Relax" mode), a wider setting increases their power ("Running - Strong" mode), and the intermediate position offers a comfortable "Jogging - Comfortable" workout. This allows you to move freely from a relaxing session after work to intense muscle activation - without changing equipment.Deep muscle activation with 200 W of power and 13 mm amplitudeAt the heart of the device is a powerful 200 W motor that generates vibrations with an amplitude of 13 mm. These parameters translate into deep muscle stimulation – even those that are difficult to reach during classic training. The result? Better muscle tone, improved circulation, support for body shaping, and greater effectiveness of every minute of exercise.Stability and safety – train confidently, without worryThe platform has been designed for maximum stability. Non-slip suction cups prevent the device from moving, and the shock-absorbing design reduces shocks and vibrations transmitted to the floor. The wide surface (72 × 38 cm) ensures comfort even for people with a larger body build, and the maximum load capacity of 200 kg allows you to train without restrictions.User-friendly surface and clear displayThe soft, skin-friendly silicone mat increases grip and comfort during exercise, even when barefoot. The centrally located LED display allows you to monitor the time and operating mode in real time. Everything is intuitive and clear, so you can focus solely on your workout.Training with music – built-in BluetoothThe built-in Bluetooth module (2.4 GHz) allows you to connect the platform to your smartphone and play your favorite music while exercising. Training becomes a pleasure, and the rhythm helps you stay motivated. It's a detail that really affects your regularity and commitment.Included in the set MERACH MR-2440P1 vibration platform x1 Remote control x1 Resistance band x1 Power cord x1 User manual x1 Manufacturer MERACH Model MR-2440P1 Rated power 200 W Vibration amplitude 13 mm Maximum load 200 kg (440 lbs) Device dimensions 72 × 38 × 16 cm (720 × 380 × 160 mm) Net weight 10.5 kg (23 lbs) Platform width 72 cm Power supply 220–240 V ~ 50/60 Hz Display LED Wireless connectivity Bluetooth
