Key Features

Built to the spec
clinicians trust.

01

Pressure Redistribution

Foam, gel, and alternating-air overlays redistribute pressure under at-risk body prominences — a core element of pressure-injury prevention bundles.

02

Positioning Precision

Bolsters, wedges, and leg elevators hold anatomical positions for surgical recovery, respiratory support, edema control, and contracture prevention.

03

Clinical-Grade Sheets

Fitted hospital sheets, stretched-fit pillowcases, and contoured bedding survive institutional laundering and fit hospital mattresses (typically 36 × 84 inches).

04

Washable and Replaceable Covers

Removable, launderable covers on overlays and positioning aids allow infection-control cleaning between patients without replacing the core foam.

Clinical Use / Bedding, Mattresses & Positioning

How clinicians
use this product.

Hospital bedding and patient-positioning equipment — beds and bed parts, bolster rolls, wedges, leg elevators, mattress overlays, fitted sheets, and pressure-redistribution surfaces. Selection is driven by patient risk (Braden score), body habitus, and care-setting protocols.

Indications

Clinical use cases.

Pressure-injury prevention in immobile and at-risk patients (Braden ≤18)
Post-operative positioning (supine with leg elevation, semi-Fowler, prone)
Respiratory support (head-of-bed elevation to prevent VAP)
Edema and circulation management (leg and arm elevation)
Contracture prevention in long-term-care and neuro rehab

Application Technique

Step by step.

01

/ 05

Assess Braden score.

Patients with Braden score ≤18 or other risk factors (immobility, incontinence, malnutrition) need active pressure-redistribution surfaces, not just foam pads.

02

/ 05

Position per clinical need.

Head-of-bed ≥30° for VAP prevention; leg elevation above heart for edema; prone or lateral for respiratory support. Reposition at least every 2 hours.

03

/ 05

Select surface match.

Foam overlays for low-risk patients; alternating-air or low-air-loss for moderate-high risk; bariatric-rated surfaces for patients over standard weight limits.

04

/ 05

Inspect and launder.

Inspect bedding daily for soiling or wear. Launder sheets per facility protocol; wipe overlays and positioning aids between patients with healthcare disinfectant.

05

/ 05

Document repositioning and skin assessment.

Log turn schedule, skin assessment (every shift), and any Stage 1+ pressure changes. Adjust surface and frequency based on assessment.

Contraindications & Cautions

When not to use.

Pressure-redistribution surfaces are not a substitute for scheduled repositioning
Bolsters and wedges must not be positioned where they compress vascular or nerve structures
Air mattresses must be monitored — deflation is a silent failure that negates all pressure-relief benefit
Do not exceed the mattress or overlay weight capacity (bariatric patients require bariatric-rated surfaces)

Frequently asked.

Answers to the questions clinical buyers and care teams ask most about this product category.

What size are hospital fitted sheets?

Standard hospital mattresses are 36 × 84 inches. Fitted sheets are sized for this plus mattress depth (typically 6–8 inches). Bariatric beds (42 or 48 inches wide) require bariatric-sized sheets.

When is a mattress overlay enough, and when do I need a full air mattress?

Foam or gel overlays suit low-to-moderate-risk patients (Braden 15–18). High-risk patients (Braden ≤14, existing pressure injuries, or prolonged immobility) typically need alternating-air or low-air-loss full mattresses — or a powered replacement mattress.

Are these mattress overlays reusable between patients?

Yes, with proper cleaning. Wipe the nylon or vinyl cover with a healthcare-grade disinfectant between patients. Remove and launder the cover if it's washable. Replace if visibly worn or contaminated.

What's the difference between a bolster, a wedge, and a roll?

Bolsters are cylindrical for side-lying support and between-knees comfort. Wedges are angular for head-of-bed or body-side elevation. Leg/heel rolls are smaller and positioned to offload specific pressure points.

Do these support bariatric patients?

Check the weight capacity. Standard overlays rate 250–350 lbs; bariatric-rated surfaces support 500–1000+ lbs. Always match the weight rating to the patient with a clinical safety margin.
