The Features Offered by a Rize Tranquility Base

The Benefits of Pairing an Adjustable Base with your Mattress

The Tranquility II provides up to 70 degrees of movement for perfect positioning.  Relax in the preset zero gravity position, or reprogram it to your favorite setting with the programmable remote.  This economical model is also designed to have zero clearance so it can fit on top of platform or pedestal beds.

An adjustable base is very beneficial for people who suffer from medical ailments. I've said the same thing in several of my reviews for power beds. People who suffer from arthritis, sleep apnea, acid reflux, and many other ailments can sleep easier when adding a power base to their bed.

Some people don't get their best comfort when lying flat on a mattress to sleep. These people sometimes pile pillows up to lift their heads up. Others bunch up the blankets under their legs so that they can sleep peacefully. Adding an adjustable base to your bed does these things for you. You won't have to go to extraordinary lengths to get comfortable.

More about Mantua Mfg.

Mantua Manufacturing Company has been a family-owned and operated business since 1952.  They named themselves after the small town in Ohio where they first got started, Mantua. An interesting fact about their manufacturing process is that they use recycled railroad steel in many of their bed frames. This is not only environmentally friendly but also ensures that their frames are much more sturdy than most others. They are so confident of their durability that they offer a lifetime warranty. If one of their frames breaks from defective material or workmanship they'll replace it at no cost.


You would have a hard time finding the features in the Rize Tranquility Adjustable Base at its price in another base. This base represents good quality American-made craftsmanship at an affordable price. Mantua manufactures its high-quality adjustable beds in Ohio.

Having the Zero Gravity feature in an entry-level base is quite surprising. This type of functionality is usually reserved for higher-end models. Another surprising feature is the weight capacity of 850 pounds. Thinner bases like this usually run about 600-700 lbs. capacity. This type of durability is virtually unmatched in a base of this type and price. For an entry-level adjustable base the tranquility offers more benefits than most others.

A Tranquility II Adjustable Base is a really good choice for people who cannot afford the super-expensive higher-end bases. You can save a lot of money while adding a high-quality base to your bedroom.
