Reflex 40H Foam Sheets

Description

Reflex 40H Firm Foam Sheets – High Density Upholstery Foam

Our Reflex 40H firm foam sheets are a strong, supportive and versatile choice for customers who need a reliable high density upholstery foam sheet for home, commercial, leisure or DIY use.

This grey Reflex 40/135 foam has a 40 kg/m³ density and a 135 Newton medium-firm feel, making it a practical option for seating, cushions, benches and general upholstery jobs where the foam needs to offer both comfort and long-lasting support.

It is a good “proper job” foam grade — firm enough to support everyday seating, but not so hard that it feels like sitting on a church pew from 1954.

✅ What Is Reflex 40H Foam Best Used For?

Reflex 40H foam sheets are suitable for a wide range of upholstery and seating applications, including:

• Sofa and chair cushion replacements
• Dining chair pads
• Bench seat cushions
• Window seat cushions
• Footstools and headboards
• Caravan and campervan seating
• Boat cushions and berth seating
• General upholstery repairs
• DIY foam projects
• Commercial seating where a firmer foam feel is required

Because Reflex 40H is a high density, fatigue-resistant foam, it is especially useful for seating areas that see regular everyday use.

🛋️ Firm Foam Sheets for Cushions, Seats & Upholstery

If your old cushions have gone flat, soft or saggy, replacing the foam can make a huge difference. Reflex 40H is designed to provide a medium-firm seating feel, helping cushions hold their shape better than lower density budget foams.

This makes it a sensible choice for:

Replacement sofa cushions where extra support is needed
Dining chair foam pads that need to feel supportive, not spongy
Bench cushions for homes, cafés, reception areas and waiting rooms
Window seat cushions where comfort and shape retention both matter
Campervan and caravan seating that doubles up as occasional sleeping space

For customers who already have covers and simply need new foam inserts, Reflex 40H can be a strong option when a firmer finish is preferred.

🚐 Suitable for Caravans, Campervans & Boats

Reflex 40H foam sheets are also popular for caravan seating, campervan cushions, boat cushions and leisure vehicle upholstery.

In these areas, cheap soft foam often breaks down quickly because cushions are used for sitting, lounging and sometimes sleeping. A higher density foam like Reflex 40H gives a firmer, more supportive feel and can be a better long-term choice for regularly used leisure seating.

For made-to-measure pieces, awkward shapes or reduced waste, you may find it easier to order through our Foam Cut to Size service rather than buying a full sheet and cutting it yourself.

✂️ Foam Sheets or Foam Cut to Size?

Buying a foam sheet can be useful if you need several pieces, want to cut the foam yourself, or have a larger upholstery project.

However, ordering a full foam sheet is not always the cheapest or easiest route. Once you factor in waste, measuring, cutting time and the risk of mistakes, many customers are better off using our Foam Cut to Size service instead.

Choose Reflex 40H foam sheets if you want:

• A half or full sheet for multiple projects
• The flexibility to cut pieces yourself
• A high density grey upholstery foam
• A firm/medium-firm foam for seating and cushions
• A practical foam grade for everyday use

Choose Foam Cut to Size if you need:

• Exact cushion sizes
• Shaped foam inserts
• Cleaner, professional cutting
• Less waste
• Foam made to fit existing covers
