Frequently Asked Questions
1. What is a pressure redistribution mattress?
A pressure redistribution mattress is a therapeutic mattress designed to spread body weight evenly across a larger surface area, reducing the concentration of pressure on vulnerable bony prominences such as the heels, sacrum, and hips. This helps prevent and manage pressure injuries in individuals who spend extended time in bed.
2. Who is the Gravity 9 mattress designed for?
The Gravity 9 is designed for individuals with limited mobility who spend extended time in bed, as well as those at risk of developing pressure injuries. It is commonly used in long-term care facilities and home care settings.
3. What is the weight capacity?
The Gravity 9 mattress supports up to 450 lbs (approximately 204 kg).
4. What sizes are available?
The Gravity 9 is available in multiple sizes including 39"W x 80"L x 6"H, 42"W x 80"L, 42"W x 84"L, 76" length, 80" length, and 84" length. Contact Must to confirm which size is right for your bed frame.
5. What is visco-elastic memory foam and why does it matter?
Visco-elastic memory foam is a pressure-sensitive foam that conforms to the shape of the body in response to heat and weight. The full top layer of open-cell visco-elastic memory foam in the Gravity 9 improves immersion and pressure redistribution, reducing peak pressure points that can lead to skin breakdown.
6. What are the articulation cuts on the bottom layer?
The bottom layer features horizontally scored articulation cuts that allow the mattress to flex and conform when the bed is adjusted (e.g., head or foot elevation). This extends the durability and life of the mattress by reducing stress on the foam during repositioning.
7. How does the heel section work?
The heel section is sloped with a channel-cut foam center that offloads pressure from the heels — one of the most vulnerable areas for pressure injury development. This design helps protect users who spend extended time in bed from heel ulcers.
8. What is the cover made of and can it be removed?
The cover is made of polyurethane stretch fabric. It is removable, fluid resistant, low shear, and vapor permeable — helping protect the skin from friction and moisture while allowing air circulation. Replacement covers are available separately.
9. Is this mattress latex-free?
Yes. The Gravity 9 is constructed with multiple layers of latex-free foam, making it suitable for individuals with latex allergies or sensitivities.
10. Does it come with raised side rails?
The Gravity 9 is available with or without raised side rails (elevated perimeter). Model 15977 includes an elevated perimeter. Contact Must to confirm which configuration is right for your needs.
11. What flammability standards does this mattress meet?
The Gravity 9 meets CFR 1632 (Standard for the Flammability of Mattresses) and CFR 1633 (Standard for the Flammability of Mattress Sets), ensuring it meets federal safety requirements for residential and care facility use.
12. What warranty does this mattress come with?
The Gravity 9 comes with a 15-year limited warranty on the foam and a 3-year warranty on the cover, reflecting the long-term durability of this premium mattress.
13. Will this mattress fit my adjustable bed?
The Gravity 9 is available in multiple sizes designed to fit standard adjustable and long-term care bed frames. Contact Must with your bed frame dimensions and we'll help you select the correct model.
14. Is this covered by extended health insurance or provincial programs?
Therapeutic mattresses for pressure injury prevention may be covered by extended health plans or provincial programs when recommended by a care provider or wound care specialist. Must can provide a receipt and product documentation to support your claim.
15. Do I need a prescription to purchase this mattress?
No prescription is required to purchase this mattress. You can order it directly from our showroom or online with local delivery available across Metro Vancouver and the Fraser Valley.
16. Can an occupational therapist or wound care nurse recommend this mattress?
Yes. Pressure redistribution mattresses are frequently recommended by occupational therapists, wound care nurses, and care providers for individuals at risk of or recovering from pressure injuries. Our team can work with your care provider's recommendations.
17. How do I clean the mattress cover?
The removable cover is fluid resistant and can be wiped down with a damp cloth and mild disinfectant for routine cleaning. For a more thorough clean, remove the cover and follow the manufacturer's laundering instructions. Contact Must for specific care guidance.
18. Are replacement covers available?
Yes. Replacement covers are available separately. Compatible cover models include 15970C, 15977C, 15984C, and 15996C depending on your mattress model. Contact Must to order the correct cover for your mattress.
19. Can this mattress be used at home?
Yes. While designed for long-term care settings, the Gravity 9 is equally suitable for home use — particularly for individuals spending extended time in bed, recovering from a procedure, or at risk of pressure injuries. Must can advise on the best setup for your home care needs.
20. Where can I buy this in Metro Vancouver or the Fraser Valley?
You can purchase the Drive Gravity 9 mattress at the Must showroom or order online with local delivery.
