The Tranquility II from Rize features all you need for better sleep, plus it is the model we recommend as best adjustable base for side sleepers. The ideal position for a side sleeper on an adjustable base is a very slight lift of both the head and foot portion of the adjustable base. This requires extra strain on the motors making the Tranquility II with its heavy-duty motors more than suitable to hold the side sleeper position.

This great model includes everything you expect to find in an entry-level model plus some extra benefits that the Rize brand offers with its adjustable bases. So if you are looking for an adjustable base with all the necessities of an adjustable base and you don't want to spend the money you would need for a high-end adjustable base then the Tranquility II would be a great choice for you.

The standard features you'll find with this adjustable base are great. It features adjustable head and foot sections allowing you to adjust the base to whatever positions you like. A wireless programmable remote with 2 preprogrammed positions Zero Gravity and Flat. It also has detachable legs that attach to raise the bed height or come off to make the base zero clearance giving it a total height of 4.5 inches.

This adjustable base also has a greater lift capacity than competitors in this price range, being able to lift up to 850 pounds. This is in part due to the heavy-duty lift motors and the fact that this base has 6 legs rather than 4. Rize also offers a 5-year full warranty followed by a 15 year prorated warranty for a total of a 20-year warranty.

Overall the Tranquility II has several great features that you wouldn't find in an entry or mid-level adjustable base, so if you are looking for a base with many great features but still at an affordable price then the Tranquility II is a great choice for you.
