These aren't competitors but two opposing views of sleep. Tempur works with memory foam that moulds to your shape through body heat; Hästens with natural fibres and springs that spring back and carry moisture away. Anyone who sleeps warm or turns a lot feels that difference most strongly — and usually in favour of springs.
Memory foam derives its action from heat: the material softens where your body warms it and moulds to you. That gives the characteristic feeling of sinking in and staying in one place.
Springs and natural fibres do the opposite. They spring back, they let air and moisture through, and they hold no shape. You move on them more easily, and the bed carries heat away instead of holding on to it.
Neither is objectively better. But they are so different that the choice is rarely about price: once you know which of the two feelings suits you, the rest is detail.
If you sleep warm, that is the most important fact. Memory foam is warmer by nature; natural fibres carry moisture away. Anyone waking at night because they are overheating feels that difference every night.
If you turn a lot, what counts is how easily you change position. In memory foam you have to work your way out of the shape already there; on springs you simply turn.
Then there is lifespan: memory foam loses its properties gradually and is replaced after eight to ten years, while a Hästens carries a warranty of up to twenty-five years on the construction. That makes the price difference per night smaller than it looks per unit — though it stays considerable.
If you want the feeling of sinking in and staying in one place, and you sleep cold rather than warm, memory foam is a logical choice and saves you a multiple.
If you want a dry sleeping climate, you move a lot, or you want a bed that stays for twenty years: only then does the conversation about natural fibres make sense. We sell Hästens, so weigh that in — but this distinction is not something we invented.
Different, and that isn't an evasive answer here: they are two opposing principles. Memory foam moulds to you and holds heat, springs and natural fibres spring back and carry heat away. Which of the two suits you isn't a question of quality.
As a rule yes. Horsehair, flax, cotton and wool carry moisture away and let air through, while memory foam derives its action from heat. For anyone who sleeps warm that is often the decisive difference.
