Power Sleep Side-Sleep Anti-Snore Pillow is designed to improve sleep posture and maintain airway openness by reducing snoring caused by back sleeping. Based on sleep medicine and ergonomic principles, the pillow uses a patented contoured structure to naturally encourage side sleeping and reduce airway obstruction during sleep. The pillow features a curved central elevation and side-support zones that help guide the head away from the supine position while providing stable neck support and improved side-sleep comfort. It is available in S, M, and L sizes to fit different body types and sleeping habits. The pillow adopts a dual-layer structure with a high-support latex core for stability and posture support, combined with a softer memory foam surface for pressure relief and comfort. According to human testing and sleep data observations conducted with Linkou Chang Gung Memorial Hospital, users showed reduced snoring frequency and improved blood oxygen performance after use. The product is suitable for positional snorers, back-sleep snorers, and individuals seeking better sleep quality and healthier sleep posture.

This product is a sleep aid and health care product, not a medical equipment. At present, it can be legally listed and sold according to regulations. Taiwan's new patent certificate M489598 has been obtained.

PowerSleep collaborated with a medical center to evaluate whether a side-sleeping anti-snoring pillow reduces snoring in mild-to-moderate obstructive sleep apnea syndrome (OSAS) patients, accounting for body weight as a potential confounder. 25 adult OSAS patients (supine AHI : non-supine AHI ≥ 2) participated. They used their own pillows on Night 0 (N0), and the anti-snoring pillow on Nights 1 (N1) and 2 (N2) at home. Primary outcomes included subjective snoring severity (SS, 0–10 visual analog scale) and objective snoring index (SI, events/hour via acoustic analysis), recorded over three consecutive nights. From N0 to N2, the entire cohort showed significant improvements, with median SS dropping from 5.0 to 4.0 and median SI from 218.0 to 115.0 events/hour. In the overweight subgroup, SS improved significantly while SI did not. However, normal-weight patients demonstrated significant improvements in both SS and SI.

The pillow’s core and memory foam are produced by a specialized manufacturing partner using automated, computer-controlled injection molding, followed by strict appearance, weight, and hardness checks. Upon arrival at our quality control facility, these components undergo a second evaluation—including odor and pressure resilience testing—to ensure absolute consistency. We enforce a strict 3% defect rate threshold for full-batch rejection. Additionally, our fabrics are crafted by a premium textile supplier. After passing appearance and odor inspections at our facility, the fabrics are stitched into covers. Our QA team then assembles the core and cover, performing a final meticulous inspection before packaging.

Designed around side-sleeping mechanics, the pillow effectively reduces snoring as long as a side-sleeping posture is maintained. If initial results don't meet expectations, you can track your sleep using a "snoring analyzer app." If measurements show less than a 20% improvement, please contact us for further assistance. Due to the product's functional nature, true validation relies on real-world consumer feedback rather than just factory data.

All materials comply with EU REACH standards, RoHS testing, and Lenzing Certification, ensuring they are completely safe, non-toxic, and well within international safety limits. Detailed reports are attached in the appendix.

GREEN-SWEET MATTRESS CORP., Ltd. implements a streamlined, multi-stage quality control system for its "Side-Sleeping Anti-Snoring Pillow". For Incoming Quality Control (IQC), the company works with ISO 9001:2015 certified partners and professional fabric suppliers to ensure source stability. All materials undergo strict EU REACH and RoHS safety testing via SGS and TÜV Rheinland—ensuring SVHC levels are ≤ 0.1% with zero heavy metals—and carry Lenzing certification to eliminate skin sensitization risks. For In-Process and Final Quality Control (IPQC/FQC), final assembly is centralized at the Yingge factory, where strict QA patrols monitor tech-latex lamination and the precise angles of the ridge-shaped structure. Personnel double-check all height specifications to guarantee the pillow 100% achieves its airway-opening, side-sleeping design. Finally, a cross-departmental task force (manufacturing, QA, and customer service) handles rapid response, instantly intercepting inventory and tracing root causes if any batch anomalies occur, ensuring no defective products reach consumers.

To ensure post-market safety, efficacy, and satisfaction, the company integrates digital tools and retail stores into its surveillance and crisis management system. For Post-Market Monitoring, customer service proactively follows up via official LINE@ within one week of purchase to track user adaptation. Customers are also guided to use a "Snore Analyzer APP" to convert subjective feedback into quantifiable, objective data for efficacy evaluation. Regarding Corrective and Preventive Actions (CAPA), if app data or feedback shows less than 20% initial improvement, a corrective mechanism triggers immediately. For users with broader shoulders or insufficient turning resistance, specialists will insert 1.5 or 2 cm reinforcement pads to dynamically optimize the side-sleeping alignment. For Crisis and Refund Management, if pad adjustments fail, the task force provides professional medical referrals for potential severe OSAS patients to prevent delayed treatment. Additionally, retail stores offer a full "money-back guarantee" for ineffective results, routing case data back to R&D and QA for continuous product optimization.

The clinical research on this product was published in Scientific Reports (2015), titled "Treatment of snoring with positional therapy in patients with positional obstructive sleep apnea syndrome." Evaluating patients with mild-to-moderate positional obstructive sleep apnea syndrome (OSAS), the study confirmed that the product significantly reduces both the objective snoring index and subjective severity. Furthermore, this academic work won 1st place in case presentations from the Taiwan Society of Sleep Medicine and 4th place from the International College of Surgeons.

Regarding the product's unique structure and functional design, the applicant has successfully obtained patent certifications across three jurisdictions, including Taiwan Utility Model Patent No. M401395, Japan Patent No. 3191987, and China Patent No. ZL 201120023525.9. These core patent technologies are closely related to the ridge-shaped anti-snoring structure designed to guide side-sleeping.
