Foam and Spring Guides
What to know when choosing a material
These guides answer, one at a time, the questions that come up when choosing foam and mattress springs. Each one opens with a question and answers it in the first paragraph; detail, a technical table and frequently asked questions follow below. Where a figure is specific to a product, the guide links to that product's page rather than asserting it.
Foam
- What Is Rebonded Foam, and How Is It Made?Rebonded foam is a high-density material made by pressing reclaimed foam pieces. How it is produced, where it is used, and what to check before buying it.
- Bondex, Granür and Rebonded Foam: What Is the Difference?Bondex, granür and rebonded foam are three names for one material. Where each name comes from, what really differs between offers, and how to compare them.
- What Is Foam Density (DNS), and How Does It Differ From Hardness?DNS is foam density in kilograms per cubic metre, not hardness. What it measures, how to verify a claimed figure with a scale, and how RG maps to it.
- What Are the Technical Specifications and Sizes of Rebonded Foam?Which specifications belong on a rebonded foam datasheet, what each one means, and exactly what to send a supplier so quotations come back comparable.
Springs
- What Is a Pocket Spring Unit, and How Does It Work?A pocket spring unit encloses every coil in its own fabric pocket, so each compresses on its own. Construction, independence, naming and roll-packing.
- What Is the Difference Between Pocket Springs and Bonnell Springs?In a Bonnell unit the coils are tied together; in a pocket unit each coil works alone. What follows from that difference, and which unit suits which product.
- What Does Coil Count Mean in a Mattress?Coil count is the total number of springs across a standard double size. What the number does and does not tell you, and how to read it with wire gauge.
Felt and Roll
- What Is Termowat (Thermobonded) Felt, and How Does It Differ from Standard Felt?Termowat felt is felt whose fibres are bonded by heat. How it differs from needle-punched felt, where it sits in a mattress, and what to specify.
- What Goes Under a Carpet? Felt Compared With Rebonded FoamFelt or rebonded foam under a carpet? Felt stops slipping and wear; rebonded foam adds softness and damps footfall. How to choose and how much to order.
- How Do You Choose Roll Foam? A Thickness and Use GuideRoll foam is supplied at 0.8 cm, 1 cm and 1.2 cm. What each thickness changes, how it is used in lamination, and what to settle when you order it.
Applications
- Which Foam Should Be Used for Soundproofing?Absorption and insulation are different problems. Where a foam layer genuinely helps, where it does not, and what actually stops sound between spaces.
- Which Foam Is Used for a Gym Floor?The foam layer in a gym floor absorbs impact energy, and density decides how well. Specifying zone by zone, why soft layers bottom out, and what to order.
Sourcing
- Materials Used in Mattress Manufacturing: A Sourcing GuidePocket springs, felt, rebonded foam and roll foam: what each layer of a mattress does, and the specifications that make two quotations comparable.
- Is Rebonded Foam Really a Recycled Material?Rebonded foam is made from foam offcuts left by cutting and upholstery work. How reclamation works, why it is not a lesser material, and what to request.
- How Do You Evaluate a Foam and Spring Supplier in Turkey?Manufacturer or trader? How to verify a Turkish foam and spring supplier you cannot visit, write an enquiry that comes back comparable, and choose packing.
