The GelFlex Gel-Infused Memory Foam Mattress is a bespoke, made-to-measure mattress, designed for cooler sleep, pressure relief, and long-term support. Unlike off-the-shelf cooling mattresses, this product is built to your exact requirements — not forced into standard sizes.
Every GelFlex mattress features a 2″ (5 cm) top layer of gel-infused memory foam, helping disperse heat and reduce temperature build-up while gently contouring to the body for comfort and support.
Gel-infused memory foam is designed to address one of the biggest complaints about traditional memory foam — heat retention. The cooling gel helps draw heat away from the body, maintaining a more comfortable sleep temperature throughout the night.
This makes GelFlex an ideal choice for:
Hot sleepers
Warm bedrooms
Campervans and motorhomes
Boats and confined sleeping spaces
You still get the pressure-relieving benefits of memory foam, without the “sleeping in treacle” feeling.
This mattress is handmade to order and can be produced in any size or shape required.
Customers simply choose a few options and provide their dimensions. We take care of the rest.
You can specify:
Length, width, and overall thickness
Rectangular or custom shapes (cut corners, tapers, angled ends)
Comfort level: Firm, Medium, or Soft
At last, sleep engineering that was once limited to standard mattress sizes is now available in customer-defined shapes and sizes.
When it comes to foam mattresses, volume equals support. The thicker the mattress, the more material there is to absorb weight, distribute pressure, and maintain comfort over time.
With GelFlex, customers choose the overall mattress thickness, allowing support levels to be tailored to personal preference and application.
Firm – maximum support and stability
Medium – balanced comfort and support
Soft – enhanced pressure relief and comfort
Every option includes the same 2″ (5 cm) gel-infused memory foam top layer, supported by a deeper base layer that provides structure, durability, and long-term performance.
Simply put: more thickness means more support.
Beneath the gel memory foam sits a durable support base, designed to keep the mattress stable and supportive over time.
Suitable for:
Domestic beds and frames
Boats and marine use
Built-in furniture and custom platforms
Every GelFlex mattress is finished with a premium Tencel® cover, selected for its breathability, moisture control, and soft feel.
Tencel works alongside the gel-infused foam to improve temperature regulation and help keep the sleep surface fresh and comfortable.Each cover is handmade to order for a precise, tailored fit.
