Naturally Tuscan, Built for Two

The Grande Dual 12 is dedicated to sleepers who want genuine comfort without compromising on the environment. It's built with a GOTS-certified organic cotton cover — the fabric is independently certified by the Institute for Ethical and Environmental Certification as made from certified organic materials — over a firm-support, 12" core.

What sets the Grande Dual 12 apart is Dual Core technology: unzip the cover and flip the inner cores to switch between two distinct comfort levels, Super Soft and Medium Soft. In Queen and King, each partner's side flips independently, for up to four different comfort combinations on one mattress.

Built For

Certified Organic

GOTS-Certified, Top to Bottom

The Grande Dual 12 is part of Magniflex's Toscana Cotton line — the only Magniflex mattress line certified to the Global Organic Textile Standard (GOTS). The organic cotton cover is verified by the Institute for Ethical and Environmental Certification, so "organic" here means an independently audited standard, not just a marketing claim.

Couples

Two Sleepers, Two Choices

Dual Core technology lets you flip the mattress core to move between Super Soft and Medium Soft comfort. In Queen and King sizes, each side flips independently, so you and your partner don't have to compromise on feel.

Italian Heritage

Handcrafted Since 1962

Magniflex has built mattresses in Prato, Italy since 1962, producing roughly 10,000 mattresses a day for customers in 99 countries. Every mattress is vacuum-compressed for shipping — a patented process that shrinks shipping volume by about 90% and fully decompresses within 24 hours of unboxing.

Construction

What's Inside

  1. 1 Organic Cotton Cover — GOTS-certified, removable and easy to dry-clean, cool and soft to the touch. A 3D band around the perimeter boosts breathability for a fresher night's sleep.
  2. 2 Memoform Padding — adapts to the shape of the body in a natural way, working alongside a Super Soft fiber layer for added softness and breathability.
  3. 3 Dual Core Comfort Layer — flip the core to choose your side. "Super Soft" combines Memoform (2") with Eliosoft (1") for a plush, cozy feel; "Medium Soft" uses an Eliosoft layer for anatomical, cozy support.
  4. 4 Eliosoft Base Layer (7½") — a high-density microcellular foam base that offers balanced support and helps align the shoulders, back, and limbs.
Feel & Support

Firm Support, With Flexibility Built In

The Grande Dual 12 is a firm-support mattress at its core, but Dual Core technology means "firm" isn't the only option available to you. Flip either side of the mattress to move between Super Soft and Medium Soft — no need to buy a different mattress if your comfort preference changes.

Why it matters:

  • Firm foundation — a supportive, minimal-sink base feel
  • Flip to adjust — Super Soft or Medium Soft, your choice
  • Independent sides — Queen and King let each partner pick their own comfort
Profile Height

A Substantial 12" Profile

The Grande Dual 12 holds a 12" profile across every size in the collection.

Why it matters:

  • Consistent height — the same profile no matter which size you choose
  • Frame-friendly — fits standard bed frames, platform beds, and adjustable bases
Made to Last

Italian-Made, Backed for the Long Haul

10-Year Limited Warranty: The Grande Dual 12 is made in Italy and backed by Magniflex's 10-Year Limited Warranty against defects in workmanship and materials, so your investment is protected for years of use.

10-YEAR LIMITED WARRANTY

Magniflex is pleased to provide you with a 10-year limited warranty to protect against any potential workmanship or material defects in our mattresses. The limited warranty for mattresses remains in force for ten (10) years and is valid from the date of purchase. The original purchase receipt is required as proof of purchase. This limited warranty is to the benefit of the original purchaser of the product. It is not transferable. This warranty, with the exception of fabric or handles, covers any visible indentation exceeding one and one-quarter inches (1 1⁄4”) on one side of the mattress. In cases where identical materials are unavailable for repair or replacement, we will substitute materials of equal quality. To ensure the effectiveness of this warranty, please use the mattress in conjunction with a firm, non-spring foundation, such as a slatted/grid top bed base, Magniflex foundation, or similar hard surfaces. These options guarantee proper center support and ventilation. Your satisfaction and comfort are our top priorities. Do not use a box spring foundation or foundations with inadequate center support, as they are likely to cause defects in the mattress, which are not covered under this warranty.

Exclusions from Mattress Coverage:

Our mattress limited warranty shall NOT apply in the following circumstances:

  • Wear and tear of the product due to normal use.
  • If the product is found to be unsanitary, dampened, burned, cut, stained, and/or soiled.
  • If the product is used without a proper foundation and/or inadequate center support.
  • Defects or damages resulting from accidents, misuse, abuse, neglect, unusual physical stress, alteration, improper operation, maintenance, or handling of the product.
  • If the product has any damage to the outer fabric of the cover, including wear and tear.
  • If the product is used for commercial purposes (including, but not limited to, hotels, motels, or institutional facilities) unless designed and built for commercial use.
  • If the product is not used but rather stored (whether long or short-term) in any orientation.
  • If the product was exposed to hot or cold temperatures, wet environments, and inappropriate climate conditions, including but not limited to, rain and humidity.
  • Discoloration or other cosmetic changes.
  • If the product was repaired by third parties not authorized by Magniflex.
  • Product failure caused by factors other than defective workmanship or material.

In addition to the foregoing, this limited warranty on our mattresses shall not apply to:

  • Body impressions, which are a normal occurrence in a sleep set and indicate that the upholstery layers are performing as they were designed to do by conforming to the body’s individual contours. Such compressions are natural and are not considered structural or design defects and, therefore, are NOT covered under the warranty.
  • A normal increase in the softness of the foam that does not affect the pressure-relieving qualities of the mattress.
  • A decrease in thickness or volume up to 2” for mattresses with covers quilted in natural fiber, as natural fiber tends to flatten down with time and usage or as a result of vacuum packing the mattress before shipping.
  • Handles, if present in the product.
  • Indentations NOT greater than one and one-quarter inches (1 1⁄4”).
  • Comfort preference.
  • Transportation and inspection costs.
  • Product purchased from unauthorized retailers or dealers.
  • If the original purchaser does not present proof of purchase, which shows the date, place, and price of purchase of the product.
  • Pillows and other products are not listed in this warranty.
