The Five Preset Positions of the Rize Clarity Base

Anti-Snore Position

Sleep better by using the anti-snore position to raise the head and open airways to reduce snoring. You can even do this for your sleep partner by using the app while they're asleep!

The Lounge Position

This preset position is a one-touch button setting on your remote that lowers the leg section of the base. This is similar to sitting in a chaise lounge, it helps remove stress and tension from your lower back.  It's a great position for TV watching or reading a book.

The Incline Position

Get neck support and lift your feet up for better support and relaxation. This position promotes good blood flow and is a great position for people who are using an adjustable foundation while recuperating from an illness.

The Flat Position

This one-touch position on the remote returns the bed to a normal flat position. This is a great feature because you don't have to hold down buttons to return it to flat, it makes it so much easier!

Zero Gravity

This is a sitting position first invented by NASA to help astronauts withstand the immense pressures experienced during take-offs. This sitting position elevates your legs higher than your chest which allows blood to flow back to the heart. It helps to reduce stress and fatigue and simulates a weightless feeling for optimum comfort while sitting in bed.

What Benefits are there to having an adjustable base?

Adding a power base to your bed can be very beneficial to your health and comfort. It can enhance your sleeping experience in many areas like comfort and health. One of the best benefits of using an adjustable base is for people with medical conditions. Those that cannot get out of bed for long or those that cannot lay flat while they sleep will benefit greatly from a power base. Getting the blood flowing by putting yourself into the zero-gravity position is an excellent feature for these people.

Those who suffer from other medical conditions can also benefit from using an adjustable foundation as well.  Acid reflux sufferers know that having the upper torso lifted to a higher angle while they sleep can reduce symptoms. We've already mentioned that heavy snorers benefit from a clear airway earlier in this review. One group that's close to my heart is arthritis patients. My mother suffers from Osteo-Arthritis and I bought her an adjustable base to help her with the pain associated with her condition. She finds it much easier to rest when she can sleep in a non-traditional position with raised legs.

Adjustable foundations benefit more people than just those who have medical conditions. A base like this enhances the comfort that you already get from your mattress. The positions listed are beneficial to all people. With the right mattress, you can get luxurious sleep that's better than the sleep you've had with a flat mattress. The massage feature, under-bed lighting, and continuous motion mode are premium luxury features. They're meant to make being a bed an experience rather than just a necessity. Power bases are the latest luxury feature to make your life more 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 it 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.


The Rize Clarity power base offers a lot of features at a very reasonable price. You won't find five preset positions, massage, USB ports, and under-bed lighting in any other model at this price point. This is a great option for people on a fixed income who spend most of their time in bed.

There are several features that make this adjustable bed a great deal. The massage feature is one of the best features. Imagine being able to get into bed after a rough day and your bed massages your concerns away. Add the connectivity that you get with the app on your phone, which can control your base, and you get a very luxurious sleep experience.

This base would be a great addition to anyone's bedroom, but it's particularly well suited for those who are bed-ridden. Those who are forced to spend most of their time in bed would benefit the most from adding this base to their bed. It's far cheaper than other models with these features plus it ships very quickly. The Manuta Rize Clarity II Adjustable Base is an excellent choice for anyone who wants more comfort from their bed.
