Need help with technical assistance?



To make a valid claim under the terms and conditions of the Nipponflex Mattress Warranty, you must:

  1. Read the full Mattress warranty for clarity on covered defects, what the mattress warranty does not cover, and your responsibilities.
  2. Provide valid original proof of purchase — your order receipt and number — demonstrating date of purchase and that the claimant is the original purchaser and still has the mattress.
  3. Provide photos of the legal tag proving that the legal tag remains on the bed and has not been altered, including a detailed photo of the serial number that is on the side of your product, the photo must clearly show the serial number and date of manufacture.
  4. Provide photos of the mattress uncovered and the claimed defect.
  5. For sagging, indentation and and body impression defects, provide photos of your foundation and/or rigid, solid surface or slatted bed base that is structurally capable of supporting the weight of the mattress and user(s). A proper bed frame is defined, for the purpose of this Mattress Warranty, as having at least five to six (5-6) leg support for a Queen, King, and California King Mattress, four (4) leg support for Twin and Full Mattresses. For Queen, King, and California King slatted style bed frames, there cannot be greater than five (5) inches between each slat in order to provide ample structural support for the foundation and user(s). A photo must show the total number of leg supports. Each slat needs to be a minimum of two and a half (2.5) inches wide. If slats are used without a foundation, a photo must show the slats. If a foundation is used, a photo must show the foundation without the mattress on it. If the purchaser uses an inappropriate foundation, box spring or base as determined by Nipponflex, the Mattress Warranty, without limitation, will be void. All bed frames and foundations sold by Nipponflex provide valid support.
  6. A brief narrative describing the defect and how it is affecting the performance of the mattress.
