Product Description

The 500i adjustable base by Restonic has all the bells and whistles to help create the maximum level of comfort.

Customize sleep positions for highly personalized comfort tailored to your body’s needs as well as a one touch flat button to quickly drift off to sleep.

An adjustable base can help ease discomfort from aches and pains when laying in bed with the dual head and leg articulation.

Adjustable bases allow for maximum comfort when reading, working or watching TV in bed.

Gentle massage feature promotes increased relaxation and can stimulation blood circulation and feature varying levels of intensity.

The wall hugger design helps maximize space in your bedroom.

The wireless remote also doubles as a flashlight in case you need to get up in the middle of the night. Additionally there are lights under the base too for added safety.

Why should you consider buying an adjustable base:

  • Reduce Snoring – with an adjustable foundation, you can adjust the postion of you head to help open up airways and reduce snoring.
  • Reduce Acid Reflux – slightly raising your head can also help reduce uncomfortable acid reflux, helping you to fall asleep faster and stay asleep through the night.
  • Ease Shoulder, Neck and Back Pain – Elevating your head and feet can help alleviate pressure on your lower back, allowing your muscles to relax after a long day. Because your muscles don’t have to work through the night, you can wake up more relaxed and with less pain.
  • Improve Circulation – Elevating your head and feet can help to increase blood flow to your muscles. This can help reduce tossing and turning and can lead to a deeper, more restful sleep.

*While many have told us they experience these benefits from an adjustable foundation, these claims have not been validated by medical testing. Your bed’s foundation is not a medical device. Please consult your doctor if you suffer from any of these medical conditions.
