Foam Mattress Extender by Medline
The Medline Foam Mattress Extenders provide a simple way to address gaps around compatible mattresses. Made from high-density foam with a durable, easy-to-clean Nylex cover, the extenders are available in multiple sizes for side-rail width gaps and headboard/footboard length gaps.

The Medline Foam Mattress Extenders are high-density foam accessories designed to help reduce dangerous gaps around a mattress. Width extenders are positioned between the mattress and side rail, while length extenders are positioned between the mattress and headboard or footboard. They feature a durable, easy-to-clean Nylex cover. Medline's product page currently lists the product family as Foam Mattress Extenders.
Medline Foam Mattress Gap Guard Features
The extenders are made from high-density foam, providing a firm insert that fills the open space alongside or at the end of a mattress.
The foam is enclosed in a Nylex cover designed to be durable and easy to clean, making the extenders suitable for healthcare and homecare environments.
The extenders are intended to help reduce spaces where a patient's body or limbs could potentially become trapped. Medline specifically describes the width extenders as helping reduce dangerous gaps between the mattress and side rail, while length extenders address gaps at the footboard/headboard.
Medline offers the product family in multiple dimensions so the extender can correspond to different mattress sizes and gap requirements. Current documented options include 76- and 80-inch width extenders and 36-inch length extenders, with several thicknesses.
The primary purpose is to help minimize open spaces around the mattress that could create patient-entrapment concerns.

Medline Foam Mattress Extender Buyer’s Guide
The Medline Foam Mattress Extender is a high-density support solution designed to eliminate dangerous gaps between hospital bed mattresses, side rails, headboards, and footboards. Built to enhance patient safety and comfort in homecare and medical settings, it bridges open spaces to prevent limb entrapment, fill mattress length or width voids, and create a seamless, continuous sleeping surface.
Entrapment Risk Reduction
The Medline Foam Mattress Extender directly addresses entrapment hazards by sealing the open gaps that naturally occur between standard hospital mattresses and bed frames or side rails. By closing off dangerous spaces, it significantly reduces the risk of accidental limb, torso, or head entrapment for vulnerable patients.
High-Density Foam Core Construction
Crafted from resilient, medical-grade high-density foam, the extender provides firm structural support without sagging or compressing under weight. The sturdy core ensures that the extended sleeping surface remains flush with the primary mattress for consistent weight distribution and alignment.
Durable Fluid-Resistant Nylex Cover
Enclosed in a heavy-duty Nylex outer cover, the mattress extender is designed to withstand daily medical use. The fluid-resistant, wipeable fabric creates a barrier against spills, perspiration, and incontinence, allowing quick and hygienic maintenance using standard hospital-grade disinfectants.
Flexible Size & Placement Options
Available in multiple dimensional configurations (including 36" x 2" x 8", 36" x 6" x 6", and 72" x 2" x 8"), the extender offers versatile application options. Width extenders fit securely between the mattress and side rail, while length extenders comfortably bridge spaces at the headboard or footboard to accommodate taller individuals or custom frame dimensions.
Latex-Free Patient Safety Design
Manufactured completely latex-free, the Medline Foam Mattress Extender is safe for individuals with severe latex sensitivities or allergies. Its non-irritating materials support skin health and promote a safe care environment across home and institutional settings.
Effortless Installation & Securing
Designed for straightforward, tool-free setup, caregivers can instantly position the extender into place alongside or at the ends of existing mattresses. Its firm friction fit keeps it securely anchored during bed elevation adjustments and patient transfers.
