A fixed wedge pillow does one thing at one angle. The RISE does whatever your body needs that night. Three pieces — a triangle support cushion, a triangle pillow, and a half-moon bolster — combine via magic-tape connectors into the configuration you need: high elevation for reflux relief, moderate angle for reading, bolster under the knees for back support, or any combination. Dual-density foam provides soft comfort at the contact surfaces and structural stability at the core so the configuration holds its shape through the night.
Three pieces. One system. Whatever support you need tonight.
- THREE-PIECE MODULAR — ANY CONFIGURATION: the triangle support cushion, triangle pillow, and half-moon bolster connect via magic-tape (Velcro) sides — reassemble them into a different configuration every night. High elevation for reflux and snoring; moderate angle for reading in bed; bolster under the knees for lumbar decompression; half-moon under ankles for leg elevation. One set of pieces, every use case.
- DUAL-DENSITY CALMCORE FOAM: 45D cooling-gel foam in the head and neck contour surfaces — soft enough to feel comfortable against skin and cool enough not to retain heat. 25D high-density foam in the wedge core — structural and non-compressing, so the angle you set holds through the night without the wedge gradually collapsing under your weight.
- MAGIC-TAPE CONNECTORS — HOLDS THE CONFIGURATION: Velcro connector strips on the mating surfaces hold the pieces together in whichever configuration you've assembled. The wedge pieces don't slide apart during sleep — the configuration stays the way you set it. Adjust by pulling the pieces apart; reconnect in the new shape.
- COTTON AIR-LAYER COVER — MACHINE-WASHABLE: 100% cotton air-layer fabric, 200 thread-count, zip-removable and machine-washable on a gentle cold cycle. Breathable enough for hot sleepers and smooth enough not to feel scratchy against skin. Available in Ice Silk, Classic, and Plush cover options — select at checkout.
Upper body elevation at 30–45° reduces overnight acid reflux events, opens the airway for reduced snoring, and is the clinically recommended positioning for GERD and post-surgical recovery.

How elevation and positioning reduce reflux, snoring, and pain
Elevating the upper body at 30–45° uses gravity to keep stomach acid in the stomach — the same mechanism that makes lying flat worsen reflux and sitting up relieve it. The RISE system achieves this angle without the height instability of pillow stacking. Consistent use reduces overnight GERD events measurably.
Head and upper-body elevation opens the posterior pharyngeal airway — reducing the soft-tissue collapse that causes most non-apnea snoring. The same positioning that reduces reflux also reduces snoring, making the RISE useful for both independently.
Positional pain from poor spinal alignment — lumbar, hip, or shoulder pressure — is a primary cause of nighttime waking and poor sleep quality in people without diagnosed sleep disorders. The RISE bolster configurations (knee support, ankle elevation, lumbar wedge) address the positional sources of pain that interrupt sleep.
For anyone whose sleep position is causing a problem that a flat pillow doesn't solve.
The acid reflux sleeper
Lying flat at night triggers your reflux. You've tried pillow stacking but it collapses by 2am.
The RISE assembled to full height holds its angle through the night via the structural 25D core — no pillow collapse, consistent elevation for consistent reflux reduction.
The snorer and their partner
You snore. Your partner is miserable. You've tried changing your sleep position but you roll back flat during the night.
Upper-body elevation from the RISE opens the airway and reduces snoring — and the structural wedge holds the position rather than letting you roll back to flat.
The post-surgery recovery person
You need specific elevation for a back, chest, or abdominal recovery — elevation that standard pillows can't provide at a consistent angle.
The RISE system's adjustable height and angle matches whatever elevation your recovery protocol requires, with structural foam that holds the position.
The in-bed reader
You read or watch TV in bed but have no headboard support — you're either flat with a pillow that compresses or upright against a wall.
Assemble the RISE pieces as a backrest — adjustable angle and height for reading, working on a laptop, or watching TV in bed with proper spine support.
The lumbar or knee pain sleeper
Your lower back or knees ache through the night. A flat surface doesn't provide the support your joints need for a full 8 hours.
The half-moon bolster under the knees decompresses the lumbar spine for back sleepers — the most consistently recommended positional aid for lower back pain.
Assemble the pieces. Set the angle. Sleep supported.
Choose Your Configuration
Decide what support you need — upper body elevation for reflux, knee bolster for back pain, reading backrest, or ankle elevation. The three pieces (triangle cushion, triangle pillow, half-moon bolster) combine in different configurations for each use.
3-Piece ModularConnect with Magic-Tape
Press the Velcro connector strips of adjacent pieces together. The connection holds the configuration through the night. To change the configuration, pull the pieces apart and reconnect in the new arrangement.
Magic-Tape ConnectorsPlace and Sleep
Position the assembled RISE on your bed and settle into position. The 25D high-density core holds the angle — no gradual collapse. The 45D cooling-gel contour surface is comfortable against the head and neck.
