Magniflex MagniStretch

Magniflex MagniStretch Mattress

The Magniflex MagniStretch Mattress is a foam mattress that gently stretches your spine while you sleep. Patented inclined layers inside it turn your own body weight into about 11 mm of traction along your back, in any sleeping position. A day of training and load leaves the spine 1.5 to 2 cm shorter by evening, and that traction helps restore the space between the vertebrae overnight. It is backed by two 12-month clinical studies on back and neck pain, and every one is made in the USA to an Italian design.

Italian physicians and university researchers followed 175 people with chronic lower back or neck pain for a full year, one group on this mattress and one on the MagniStretch Pillow. By the 12-month check, perceived pain had fallen 40 percent and perceived disability in daily movement 35 percent, while perceived sleep quality rose 40 percent. Both studies appeared in the Journal of Surgery in July 2025, and the American Chiropractic Association has certified the MagniStretch.

There are three MagniStretch models, each with its own foam stack under the same patented stretching construction. The MagniStretch Plush is the softest, 12 in. tall, with a softer Eliosoft foam base under the stretching layers and the gentlest, most pressure-relieving feel of the three. The MagniStretch 12 is the medium model, the same build over a firmer Elioform base. The MagniStretch Sport 10 is the firmest, a 10 in. mattress in a breathable Performance Fabric cover, made for active sleepers who want stable, responsive support with no sinking feel.

Patented stretching system

How it works

MagniStretch uses the pressure your body already puts on the mattress. Lie down, and that weight puts the inner layers to work on your spine with no effort from you.

Inclined layers that stretch
The foam layers are cut on an incline, and they move in opposite directions under your weight. That continuous pull lengthens the body from the lower back to the neck and feet, helping restore the space between vertebrae overnight.
Continuous traction
Traction that follows your weight
The stretch is proportional to the weight on the mattress, so a heavier frame gets a stronger pull. Changing position during the night creates intermittent traction, which helps the muscles along the spine relax.
Scales with your weight
Checkerboard support zones
The upper stretching layer is cut in a checkerboard pattern, so different parts of the body get their own zone of support while the stretch works underneath.
Zoned support
Outlast temperature control
The Plush and the 12 are covered in Outlast fabric, first developed for astronaut suits. Millions of microcapsules soak up extra body heat and release it again as you cool, which keeps your temperature steady instead of swinging.
Up to 48% less perspiration at night

Clinical research

The research

Each study ran for a full year, one on the mattress and one on the pillow, and each scored people on standard clinical pain, function and sleep questionnaires.

The mattress study
One hundred adults aged 20 to 75, all living with chronic lower back pain, slept on the MagniStretch mattress every night for a year. Pain, everyday function and sleep quality were scored at the start, at 6 months and at 12 months, using the standard VAS pain scale, the Oswestry Disability Index and the Pittsburgh Sleep Quality Index.
100 adults
What changed
Every age group improved on all three measures by the end of the year. Combined across both studies, perceived pain fell 40 percent, perceived disability 35 percent, and perceived sleep quality improved 40 percent.
Pain, disability, sleep
The pillow study
A second group of 75 adults with chronic neck pain used the MagniStretch Pillow every night for a year, scored on the same pain and sleep scales plus the Neck Disability Index.

How to use it

Daily compression

Overnight traction for a compressed spine

Your spine carries load all day, and the discs between the vertebrae compress under it. MagniStretch works on that compression every night, while you sleep.

  • Traction starts as soon as you lie down
  • Stretches from the lower back to the neck and feet
  • Rolling over changes the pull and keeps the traction intermittent
  • The stretch runs all night with no effort from you

The same stretch in three feels

All three models carry the patented MagniStretch stretching construction. The Plush and the 12 share the same comfort and stretching layers and differ only in the base foam, while the Sport 10 uses its own two-layer build in a Performance Fabric cover.

  • MagniStretch Plush: 1/2 in. Memoform and 1/2 in. hypoallergenic fiber over 2 in. and 4 1/2 in. Eliosoft stretching layers, on a 4 1/2 in. Eliosoft base
  • MagniStretch 12: the same comfort and stretching layers on a 4 1/2 in. Elioform base
  • MagniStretch Sport 10: 2 in. Eliosoft over 8 in. Elioform, both with MagniStretch technology
  • Outlast and Natural Viscose cover on the Plush and 12; Performance Fabric on the Sport 10

Add the MagniStretch Pillow

The MagniStretch Pillow brings the same inclined-layer idea to the neck. The weight of your head presses on the inclined layers, stretching the cervical area from the shoulders to the base of the skull.

  • Memoform top layer contours to the neck
  • Eliosoft lower layer holds the cervical curve
  • Four heights, from S at 4 in. to XL at 7 in.
  • Usable on both sides

MagniStretch questions

Frequently asked questions

Through your own weight. Lying down presses on inclined foam layers that move in opposite directions, and that applies gentle traction along the spine, about 11 mm, for as long as you are in bed.
Pick the MagniStretch Plush, the softest, for the most pressure relief and contour. Pick the MagniStretch 12, the medium model, for a firmer base under the same comfort layers. Pick the MagniStretch Sport 10, the firmest, if you are an active sleeper who wants the most stable, responsive support.
Yes. The stretch works in every sleeping position, and changing position during the night keeps the traction working.
The stretch starts the first night you lie on it. In the studies, the clearest improvement in pain and sleep showed at the 12-month check, after a year of nightly use.
No. It is not recommended after a spinal fusion, because someone with a fusion will not get the same benefit from the stretch as someone without one.

Magniflex provides a limited ten (10) year warranty against defects in materials and workmanship for eligible mattresses, beginning on the original date of purchase. Proof of purchase is required. This warranty applies only to the original purchaser and is non-transferable.

Excluding the fabric cover and handles, this warranty covers visible indentations greater than one and one-quarter inches (1¼") on one side of the mattress. If identical materials are no longer available for repair or replacement, Magniflex may use materials of comparable quality.

To maintain coverage, the mattress must be used on a firm, non-spring foundation, such as a slatted or grid-top bed base, a Magniflex foundation, or another comparable rigid support surface that provides proper center support and ventilation. Damage caused by a box spring or foundation without adequate center support is not covered.

This Limited Warranty is separate from and does not extend any applicable return, exchange, or satisfaction program offered by Magniflex. Eligibility for returns, exchanges, or comfort-related programs, where available, is governed exclusively by the applicable Returns & Refund Policy.
