Is the floor sofa cold foam or regular high-density foam?
Also asked as:Is your couch made of cold foam?Cold foam or high-density foam?
Two labels, one block of foam. The confusion was a wording problem, not a foam problem.
SaveThe quick answer
The floor sofa uses cold foam: its base mattresses are HR (high-resilience) cold foam at T28 density with an ILD of 42. That foam is also high-density, so both labels describe the same block. Each foam block sits in its own inner cover under the removable outer cover, and the backrests are filled with shredded foam.

| ILD 42 | The firmness number | A medium-hard seat |
| Shredded foam | Loose pieces, not one block | The backrests |
| Inner cover | A lining on each foam block | Yes, under the removable outer cover |

How one foam ended up with two names
The mix-up was wording, not foam. A buyer in the US noticed the website said cold foam while the marketplace listing said high density, and asked which was right. The first reply described it as high-density foam with an ILD of 42. The follow-up settled it: the workshop uses cold foam, and the listing was corrected.
Both words were true all along. HR cold foam at T28 density is a high-density foam; one label names the type, the other the weight class. The number that tells you how the seat feels is the ILD, so read it next to the density every time.
The density vs firmness Pattern explains the pair, the lb/ft³ and kg/m³ Pattern converts them, and the foam firmness finder turns them into a feel. The sofas themselves live under modular floor sofas. Which number were you comparing, partner: the density or the ILD?
A floor sofa labeled cold foam and one labeled high-density can hold the same block: HR cold foam at T28 density, ILD 42.

Buyer questions
- A common question
What foam goes into the floor sofa base, and what density?
The workshop's answerThe base mattresses are HR (high-resilience) cold foam, density T28, with an elasticity of ILD 42. The backrests are filled with shredded foam.
- A common question
Your website says cold foam and the listing says high density. Which is correct?
The workshop's answerThe workshop first described it as high-density foam with an ILD of 42, then confirmed it uses cold foam and corrected the listing.
- A common question
Does the foam inside the teddy sofa have its own cover?
The workshop's answerYes. The filling is a high-density comfort cold foam, and each foam block has an inner cover under the removable outer cover.
- A common question
Why do the sofa backrests feel like pieces instead of one block?
The workshop's answerBy design. Backrests and armrests use shredded or layered foam so they stay soft and flexible instead of rigid. Lumps usually mean the filling has shifted, and it can be reshaped by hand.
Questions buyers ask next
How long should the floor sofa's cold foam keep its shape?
The seat foam is 28-density medium-hard high-density foam, sometimes quoted as 28-32, and the workshop says it lasts for years without collapsing. The softer feel of the backrests comes from shredded foam, not from wear.
Is T28 foam density measured in pounds or kilograms?
Kilograms. T28 means about 28 kg per cubic meter, which is roughly 1.75 lb per cubic foot. Convert before comparing it with a foam quoted in lb/ft³, or the numbers will look far apart when they are not.
Can I get a floor cushion with no foam in it at all?
Yes. The tufted floor cushions are foam-free, filled with durable fiber inserts, and the bound tufting means you don't feel the buttons. On a custom order, write 'no foam' clearly in the note.
