  • The cover is made of stretch-knit polyester and spandex.

General Overview

  • The price-point of Hyphen mattresses is slightly lower than the cost of an average all-foam mattress.
  • Hyphen Sleep’s 100-night sleep trial does not include a mandatory break-in period. Comparatively, many all-foam mattress sellers require purchasers to test out their mattress for at least 30 nights before they qualify for a product refund. Furthermore, customers who return their Hyphen mattress will receive a full refund, and will not be responsible for shipping or handling charges.
  • Hyphen Sleep offers a 20-year limited warranty with a $99 surcharge for repairs or replacements that occur during years 10 to 20. By comparison, most mattress sellers with 20-year warranties divide the coverage into nonprorated and prorated periods, which can result in much higher costs for repairs or replacements.


  • Hyphen mattresses are exclusively available in a Medium Firm rating, which may be limiting for customers who prefer to sleep on mattresses that are more or less firm.
  • Hyphen mattresses are made entirely of polyfoam, which generally conforms less closely and does not alleviate as much bodily pressure as memory foam.
  • Hyphen Sleep was launched in 2015, and the long-term performance of their mattresses has not been accurately assessed.

At this time, we have not received enough customer feedback to accurately evaluate Hyphen mattresses based on sleep position and sleeper weight. We will update this section as soon as possible.

In the meantime, please note that everyone has varying experiences on different mattresses. Sleeper comfort and spinal support are the most important factors when it comes to selecting a mattress. For more information on sleeping positions please see our guides for sidebackstomach and combination sleepers.

  • Warranty Details

    Warranty: Hyphen offers a 20-year limited warranty for all mattresses.

    1. Warranty coverage begins on the date of purchase, and is divided into two periods:
      • For the first 10 years, Hyphen will repair or replace a defective mattress (at their sole option) at no cost to the owner.
      • For years 10 to 20, owners will be responsible for a $99 transportation fee if their mattress needs to be repaired or replaced.
    2. Customers have the option of replacing a defective mattress with an upgrade model. In this case, they must pay the difference between the prices of the original and the upgrade. An upgrade purchase will result in a new warranty coverage period that begins when the upgrade model is delivered; all other replacements will be included in the original warranty, and will not extend the coverage period.
    3. The warranty will be voided if a proper foundation system is not used. According to Hyphen, the mattresses are designed for use with ‘a matching foundation or adjustable bed base with a proper bed frame sufficient to support the collective weight of the mattress and foundation’.
    4. The warranty will cover the following product defects
      • Deterioration in the mattress surface that causes visible indentations or sagging that measure one inch (1″) or deeper, provided the issue is not caused by owner misuse and/or improper foundational support.
      • Manufacturing flaws related to the mattress cover, including cracked or broken zippers.
    5. The warranty will not cover the following:
      • A normal increase in foam softness that does not affect its pressure-relieving abilities.
      • Repair or replacement requests that occur due to changes in the owner’s comfort preferences.
      • Burns, cuts, tears, stains, and other types of damage that occur due to owner misuse, improper cleaning, and/or inadequate foundational support.
    6. Customers who purchase their Hyphen mattress on will be entitled to the same warranty coverage as those who buy their mattress directly from Hyphen.
    7. Warranty coverage is exclusively extended to original owners who buy Hyphen mattress from Hyphen or an authorized Hyphen dealer. Those who buy or acquire a mattress from the original owner or an unauthorized Hyphen retailer will do so ‘as is’, and will not qualify for warranty coverage.
