Main Distinguishing Features

Get ready for a chair that's as aesthetically pleasing as it is comfortable. The UltraCozy UC671 Zero Gravity Power Recliner brings together the best of both worlds. Let's explore its Zero Gravity Recliner Features that stand out:

Five Comfort Zones

The UltraComfort UC671 incorporates all five adjustable comfort zones to create the ultimate wellness experience with our patented Eclipse Technology. You'll have the option to choose from pre-programmed positions or to manually adjust to the perfect position just for you. Each Comfort Zone can be adjusted independently with the assistance of the patented AutoDrive hand control.  The 5 zones include:  Eclipse Technology to raise the seatbox up 15 degrees, complete control of the back rest, complete separate control of the footrest, power pillow, power lumbar.

Patented Stellar Positioning

While it may seem like a luxury, you will soon find that having power reclining furniture and its customized position capability is a necessity for your home.  The UltraComfort UC671 comes with the patented positioning technology which allows you to independently adjust the footrest and the backrest independently in order to facilitate positions that place the feet above the heart reducing lower back pressure and any foot swelling.  

Zero Gravity Lift Chair

The UltraComfort UC671 is one of the only zero gravity Recliner  available today in the market.  Zero Gravity was first developed by NASA scientists as a way to remove the extreme stress our astronauts' spines felt as they were launched into orbit.  By moving the legs up to heart level in the recline position, all pressure is equally distributed along the spine.  Many chiropractors believe that this is the "healthiest way to sit." 

Full-Body Comfort

Unlike recliners that are built with a two or three-piece seat and leg rest cushion, the UltraComfort UC671 Power Lift Recliner has a no-gap cushion that extends from the seat to the feet. This style offers fuller comfort and support for your legs and eliminates the open gap that toddlers can get fingers or toys stuck in.

Easy to Use Remote with AutoDrive 3.0 Technology

You will no longer have to worry about fumbling around with the remote in a dark room.  With the UltraComfort UC671 Power Lift Recliner, you will enjoy the newly upgraded and user-friendly features of the AutoDrive 3.0.  Featuring an ergonomic hand control design, the shape, as well as the finger groove on the back, make it very easy to hold.  The single button layout takes the guesswork out of operating a StellarComfort chair.  You will also enjoy Programmable Stellar Eclipse Positioning buttons where all 5 position control buttons are programmable to suit your needs precisely.  Lock Function limits or restricts hand control usage for safety or convenience should you want it. 

Built-in Cup Holder

You will no longer have to worry about you spilling your drinks with the UltraComfort UC671 built-in cup holder.

USB Charging Port

Keep your devices charged with UltraComfort UC671 convenient USB charging port.

iPad Stand & Phone Holder

Once the flaps are off, you'll find the back of the recliner and a bag of wiring tucked away. Pro-tip: use channel locks or pliers to remove any tape or zip ties that might secure the wiring.
