Want a bed frame you can adjust wirelessly to get super comfy? Our Sleepmotion 400i is available as a single, double, king or super king. You can change the height of your head and feet, as well as your lumbar support, using the wireless remote, or via our Napp app.

The 400i is perfect for supporting your back, as you recline to watch TV or read, and it features Zero Gravity technology for a weightless feeling. It also helps improve your circulation and ease painful pressure points, giving you outstanding support and comfort while you unwind or sleep. You can even switch on its massage units to take relaxation to the next level!

With its adjustable back, the 400i could help lessen the severity of snoring. During deep sleep, the muscles in the roof of your mouth, tongue and throat relax. This can partially block your airways and cause vibration, causing a snoring sound. By using the 400i to elevate your head slightly, the airways remain open, limiting the vibrations and reducing or stopping the snoring.

You can use the 400i platform on its own or have it dropped into one of our Sleepmotion compatible bed frames, depending on the look you prefer.

Looking for more ways to improve your sleeping and lounging experience? You may want to upgrade to the Sleepmotion 800i platform. You’ll enjoy even more features like head support, two USB ports and an underbed mood light.

Additional information:

A mattress isn’t included, so choose from our range of compatible mattresses.

Our Sleepmotion bases are designed for using with one mattress only. You can’t use separate mattresses for independent movement.

Images are a visual representation. It’s normal to see a slight gap between the base and mattress when in use.

For your peace of mind, our Bedcover Service Plan lets you rest easy about the looks, comfort and performance of your new mattress, bed or furniture with cover of up to 8 years.
