Aer-Fōm refers to the inner upholstery padding (below the quilt), over the Marshall pocket coil spring-core. It is a body conforming and pressure relieving material that resembles memory foams but, without any heat sensitivity or heat retention whatsoever. The Rest Assured® Heritage, Sleepmaker Luxe III and Premier First features this padding material and is regarded as a Plush (softer feeling) tight top two-sided mattress design.
CertiPUR-US® is a not-for-profit certification program for foam used in bedding products and upholstered furniture. When you see the CertiPUR-US® seal, you can be confident that the flexible polyurethane foam inside meets CertiPUR-US® standards for content, emissions, and durability, and has been analyzed by independent, accredited testing laboratories.
CertiPUR-US® approved foams are:
- Made without ozone depleters
- Made without PBDEs, TDCPP or TCEP (“Tris”) flame retardants
- Made without mercury, lead and other heavy metals
- Made without formaldehyde
- Made without phthalates regulated by the Consumer Product Safety Commission
- Low VOC (Volatile Organic Compound) emissions for indoor air quality (less than 0.5 parts per million)
CleanSleep® refers specifically to the Marshall Mattress approach to mattress making. This not only involves overall manufacturing hygiene as well as having its mattress ticking (cover fabric) finished with a bio-friendly process that safely inhibits dust mites from breeding in the sleeping environment. It is hypoallergenic, antibacterial, antimicrobial and antifungal. This process is Oeko-Tex 100 certified.
A Comfort Top is a double cushion European styled no flip mattress design where the sleep surface padding and the interior padding each contribute to the overall sensations of comfort and underlying support felt by the sleeper.
Damask Fabric refers to a reversible designed fabric of silk, wool, linen, cotton or synthetic fibres with a pattern formed by weaving. Damasks are typically woven with one warp yarn and one weft yarn. Marshall Mattress uses natural source Belgian Viscose or Cotton and Viscose blend Damask covers in its products.
Flip Mattress (Two-Sided Mattress)
A Flip, or Two-Sided Mattress refers to a mattress where both top and bottom surfaces are usable for sleep. It is implicit that for the price paid, you have two usable sleep surfaces. A benefit of the this traditional design is that once the mattress is flipped and reversed to a standard schedule, the sleep surfaces are able to recover and ensure good useful life.
Foam encasement refers to a method of mattress production where a 3” to 4” hard foam border is glued to the innerspring unit of a mattress. The foam is typically made of polyurethane and is intended to increase the sleep surface. There are many advocates and detractors of the foam encasement process. Marshall Mattress does not manufacture any of its pocket coil mattresses with foam encasement. That means that all pocket coil mattresses are from edge-to-edge and head-to-toe with no foam surrounding edges.
Hollofil™ is a synthetic pillow fibre that is breathable and pressure relieving. It is designed to be air permeable and circulate temperature evenly.
James Marshall was a British-born machinist, engineer and inventor credited with inventing the individual pocket coil spring system. He settled near St. Thomas, Ontario, Canada when he patented his invention in 1900. He was granted patents in the United States and Europe in 1901.
New Zealand Wool
New Zealand wool is a sustainable natural fibre with outstanding beauty, performance, maintenance and well-being benefits. It is non-allergenic and its natural properties provide inherent fire resistance, air purification and moisture control, creating an exceptionally safe and healthy indoor environment. Marshall Mattresses primarily uses New Zealand Wool as a top of quilt comfort layer.
No Flip Mattress (Singled-Sided Mattress)
A No Flip, or Single-Sided Mattress refers to a mattress where there is only one usable sleep surface. The best No Flip designs ensure even wear but will not have the same degree of surface recovery as a flip mattress. To ensure even wear, it’s recommended to reverse the mattress end to end periodically as directed by your warranty.
Off-Gassing refers the levels of volatile organic compounds that are emitted from a mattress or other household items. In the case of mattresses, Off-Gassing is most commonly addressed when referring to the types of foams found in each product. All foams used in the production of Marshall Mattress products are CertiPUR-US® certified. No PBDEs are ever used in any Marshall Mattress products. For more information please visit the CertiPUR®-US website or consult the CertiPUR-US® section of the glossary.
Poly Brominated Diphenyl Ethers are flame retardant chemicals produced in countries other than Canada, and appear in certain consumer products such as polyurethane foam or plastics. Such commercial use has been questioned as to safety since its residue is detectable in the environment. No PBDEs are ever used in any Marshall Mattress products.
Phthalates are a group of chemicals used to make plastics more flexible and harder to break. They are often called plasticizers. Some phthalates are used as solvents (dissolving agents) for other materials. No Phthalates are ever used in any Marshall Mattress products.
A Pillow Top is intended to be a double cushion finish to the sleep surface which involves a primary upholstery padding below the quilted cover and enhancement layers quilted to the mattress cover fabric. Marshall Mattress distinctly separates the two elements so that the user experiences graduated comfort as they rest.
A pocket coil refers to a mattress spring and cushioning system invented in Canada by James Marshall, and patented in 1900. Used in mattresses, it is considered the most well-known and most popular type of mattress construction.
Reverse Convolute Foam
Convolute Foam that is specifically sliced in an egg-crate pattern which allows for elements of pressure reduction in the surface of the mattress quilt below the cover. Reverse means that the dimples face inward allowing the maximum amount of pressure relief experienced by the sleeper All foams used in the production of Marshall Mattress products are CertiPUR-US® certified.
Soy Foam is a manmade material partially made from soy that is considered breathable, more user friendly and is more biodegradable at the end of its use. It is featured primarily as a component for inner upholstery and quilting. All foams used in the production of Marshall Mattress products are CertiPUR-US® certified.
A Tight Top is a traditional mattress finish where the top mattress panel is seamed directly to the sidewall of the mattress border. A Tight Top mattress can be constructed to offer different degrees of support and comfort from the inside out.
