Order Cancellations

Because NewLeaf strives to deliver customer orders as quickly as possible, most orders are processed and shipped the day they are ordered. Orders that are cancelled after they have shipped are subject to any applicable manufacturer restocking fees, return shipping and original shipping costs as outlined below.

Returns & Exchange Policy

Your satisfaction as our customer is our top priority. And we want you to be completely satisified with your purchase. Because many of the items offered at NewLeaf Home Medical are considered "Medical Devices," there are a few strict guidelines that need to be followed for medical compliance and hygenic reasons.

Non-Returnable Items

There are certain products that are inherently Non-Returnable due to the nature of the product, sterile/hygienic concerns, or for custom-built or "made-to-order" reasons. The following products will NOT qualify for a return if the product has been put into use: Mattresses; Mattress Pads; Bath Lifts; Incomplete Case Packs; Bathroom Safety Products; and other items that may have medical device return restrictions from the manufacturer. If a Case Pack item packaging has been opened, or if a Mattress or Bathroom Product has been put into use, it is NOT eligible for return. Custom-built or "made-to-order" products like, but not limited to Winco and Lumex recliners, Big Boyz beds, Moxi Mattresses, and patient lift products by Traxx Mobility and Lumex are Non-Returnable.

Restocking & Shipping Fees

The following supplier-sourced items are subject to restocking fees, which will be deducted from an eligible return credit based on the percentage indicated: Drive Medical (15%); Lumex/Graham Field (25%); Invacare (25%); Pride Lift Chairs and Mobility Products (20%); and Protekt Mattresses (20%).

Note: While many of our products are offered with "Free Shipping," the actual incurred ship-to costs cannot be recouped from the shipping company once your item has shipped. As a result, this cost will be deducted from your eligible return refund. Original shipping costs may be waived if exchanging for another item of same or greater value.

Return Shipping

Return shipping costs are the responsibility of the customer unless the return item(s) was damaged during shipment to you, the item you received was not what you ordered, or the return is due to a warranty issue.

Return Timeframe

You have 30 calendar days to return an item from the date your received it *If your item is not classified as a "Non-Returnable" item. If you need additional details or have questions about a product before placing your order, or if you would like to return or exchange your purchase, please contact our Customer Care Team at 888.739.4330. It is important to note that:

Items must be returned in new, unused and resalable condition.

Return items must be shipped back in the original shipping carton with manufacturer packaging.

Medical devices like Feeding Tubes, Catheters, Oxygen Tubing/Masks, Bathroom, Bedding or Mattress products, and other items with "hygienic" classifications are only eligible for return if the item packaging is unopened and unused.

State of the Art Compressor

  • Solenoid valve system allows for easy set up and effective therapy cycles
  • Four therapy cycle times of 5, 10, 15 and 20 minutes can be adjusted for patient comfort to provide alternating pressure relief

Constant Pressure Monitoring

  • Constantly monitors the air pressure in the mattress to maintain the appropriate pressure to prevent capillary occlusion (generally below 32mm/Hg)

Manual Fowler

  • When Fowler mode is activated manually, 25% more air is automatically pushed into the mattress mid-section to prevent patient from bottoming out when bed is articulated (head or foot sections raised)

Additional Features 

  • Suited for prevention and treatment of Stage I to IV pressure ulcers
  • On-Demand Low Air Loss - Improves air circulation and cools the body temperature with a unique system of air released into the mattress
  • 10 LPM (Liters Per Minute) Compressor
  • Audio and Visual Alarms - Warns patient and caregiver during power outage or low pressure
  • Lock Out Button - Prevents against tampering or accidental adjustments
  • Quick Connect Coupler - Allows for quick and easy set up
  • Power Outage Safety - Mattress will remain inflated during power outage as long as air hose remains connected to the compressor
  • Pressure Adjustment - Pressure can be adjusted by 25%, 50% or 75% to provide comfort for frail patients
  • Quilted 70 denier nylon cover helps protect user from friction and shear
  • Non-skid bottom as well as 10 nylon web buckled hold downs secure mattress to bed
