Which Memory Foam Is Best? A Simple Guide to Choosing the Right Grade

F4U MEMORY FOAM RANGE

The 3 Grades of Memory Foam We Now Offer – What’s the Difference?

Not all memory foam feels the same — and if you’ve ever wondered why one topper feels blissfully comfortable while another feels too soft, too firm, or too hot, the answer lies in the grade of foam used.

At Foam4U, we now offer three distinct grades of memory foam for our made-to-measure toppers, each designed for a different type of sleeper and comfort preference:

  • Vasco 40 – soft, classic memory foam
  • SF V50 – more supportive, premium all-round memory foam
  • GelFlex – cooler, more responsive memory foam

Below, we explain exactly what each one does best — in plain English.

1. SFV 40 Memory Foam – Soft, Classic Comfort

Vasco 40 is a traditional viscoelastic memory foam designed to prioritise comfort and pressure relief.

It has a softer feel than higher-density memory foams, allowing your body to gently sink in as the foam responds to heat and pressure. This creates that familiar “memory foam hug” that many people love.

What it feels like in use

  • Soft and welcoming
  • Strong pressure relief for shoulders and hips
  • Slower recovery, classic memory foam behaviour

Best suited for

  • Side sleepers
  • Lighter-weight users
  • Anyone wanting a plush, cushioned topper feel

If comfort is your main goal and you prefer a softer sleeping surface, Vasco 40 is an excellent choice.

2. SF V50 Memory Foam – Supportive, Premium All-Rounder

SF V50 is a higher-density memory foam that offers a more supportive and balanced feel while still retaining proper memory foam comfort.

Compared to softer grades, SF V50 provides better body support and shape retention, making it a popular “safe choice” for most sleepers. You still get pressure relief, but with less of the deep sink-in sensation.

What it feels like in use

  • Medium to medium-firm support
  • More stable than softer memory foams
  • Better support when changing position

Best suited for

  • Back sleepers
  • Average to heavier-weight users
  • Anyone who finds softer memory foam too sinky

If you want comfort and support in equal measure, SF V50 is the best all-round option.

3. GelFlex Memory Foam – Cooler, More Responsive Comfort

GelFlex is a modern memory foam designed for people who love memory foam comfort but dislike sleeping hot.

By incorporating cooling gel technology, GelFlex helps disperse heat more effectively than standard visco foams. It also tends to feel slightly more responsive, reducing that “stuck” feeling some people experience with traditional memory foam.

What it feels like in use

  • Memory foam comfort with a fresher feel
  • Slightly quicker response than classic visco
  • Designed to reduce heat build-up

Best suited for

  • Hot sleepers
  • People who overheat on standard memory foam
  • Anyone wanting modern comfort without going firm

GelFlex is ideal if temperature regulation matters as much as comfort.
