Geo-Matrix G1 Dual Zone Mattress by Blake Medical

The Blake Geo-Matrix G1 Dual Zone (G1MFD3680 at 36" x 80") is a 6" (15 cm) gel foam mattress for a hospital bed, with gel at the coccyx and the heels and no pump.

What does it do and how does it work?

• A 1.5" (3.8 cm) Geo-Matrix gel insert sits at the coccyx. Blake says it lowers peak pressure and shear when the head of the bed is raised.
• A 0.75" (1.9 cm) pillow-top gel insert sits at the heels, for pressure, friction and shear.
• Under the gel: a dual-density polyurethane base, a 5 lb memory foam core, and a firm foam border for transfers.
• The cover is 4-way stretch, antimicrobial, fluid-proof and wipeable, with nylon quilting.

Who is it for, and who should choose something else?

• Blake states it maintains skin health and aids healing of stage I to II pressure injuries (redness or a superficial wound).
• A nurse, doctor or therapist decides whether two gel zones are enough.
• Choose the G2 for gel along the whole mattress, the Infusion for gel mixed into foam when the person still moves, or alternating pressure for a pump.

Will it fit?

• Standard size is 36" x 80" x 6" (91 x 203 x 15 cm). Other widths are 39", 42", 48", 54" and 60" (99, 107, 122, 137 and 152 cm), each 80" long.
• Many homecare hospital beds use a 36" x 80" deck.
• Stock capacity is 300 lbs (136 kg). Custom capacity is 500 lbs (227 kg). A lower bed rating applies.
• Health Canada recommends gaps under 120 mm (4 3/4 in) within the rail and between the rail and the mattress, and under 60 mm (2 3/8 in) at the rail ends. Check this height with the rails.
• Confirm the width before you order. A mattress that has touched skin cannot be returned. See the return policy.

Using it day to day

• Lay it on the bare deck. Wipe the cover, or machine wash it to 60 C and hang it to dry. Do not use bleach, and do not wet the foam. Spare cover G1DRC3680 fits 36" x 80". Match any spare to the width. The firm border is foam, not a rail.

What does it work with, and what are its limits?

• It replaces the mattress. It is not a topper, and a power cut cannot deflate it.
• For a wheelchair, see the Geo-Matrix Bronze cushion. Warranty is 5 years on the mattress and 1 year on the cover: see warranty.

Which version should I choose?

• G1MFD3680 is 36" wide. Wider decks take 39", 42" or 48". A bariatric deck takes 54" or 60", still 80" long. Order 500 lbs (227 kg) only when the care plan needs it.

How does it compare?

• The G2 runs gel the full length, deeper at the coccyx, still at 300 lbs (136 kg).
• The Infusion is a 2" gel-infused foam topper on a foam base, rated 350 lbs (160 kg), with no gel columns. See other gel mattresses.
