Memory foam mattresses: what they don't tell you in the store
A memory foam layer is not the same as a mattress made entirely of that material. 90% of those sold are hybrid: a foam or spring base topped with a memory foam layer. And that's where the maze begins. The key figure they hide is the thickness of that layer: serious manufacturers use at least 6 cm; those looking to make a quick profit, 3, 2 or even 1.5 cm. And no one tells you this in the store.
Springs vs memory foam: a settled debate
Traditional innerspring mattresses have become obsolete. It's not an opinion, it's technical consensus: springs create pressure points and lose their shape sooner. The dominant alternative is memory foam, but beware: density matters. The good ones are around 85 kg/m³ (don't confuse it with kg/m², a common mistake). However, densities above 85 can harden the mattress, reduce breathability and make it cold in winter. The sweet spot is around 55-85 kg/m³.
Another stubborn myth: firm mattresses are better for your back. False. Several recent analyses show that a mattress that is too rigid can cause muscle pain because it doesn't adapt to the curves of the body. The key is support, not firmness.
Where to buy and how much to pay
Big retailers (El Corte Inglés, Carrefour) are the worst option: own brands with fancy names and 300% markups. Online you can find decent memory foam mattresses from €100 (single size). Portals like ventadecolchones.com offer factory prices and free shipping. But be careful with rolled-up models: some dry out over time and lose their shape.
For those who can afford it, Tampe or Master (the same mattress under a different label) from Aspol are a safe bet: they last over 10 years with barely any wear. And if the budget is tight, there's always the Japanese futon or the straw mattress – yes, really – though they're not for everyone.
The pending issue: breathability and materials
Classic memory foam traps heat. That's why gel layers (Novogel) have appeared that cool things down, though they're still expensive. There are also special covers that absorb moisture, like the ones some sellers recommend. But are they worth it? It depends on whether you sweat at night. And watch out for the composition: most are petroleum-based. There's no mass-market eco-friendly option yet.
What about the old-school firm ones?
Some defend firm mattresses (Bultex from Pikolin, for example) arguing that firmness should come from the bed base, not the mattress itself. It's a minority position but with logic: a slatted bed base can adjust firmness, while a soft mattress with a firm outer layer prevents sagging. In the end, the best purchase is the one you try out: no one should choose a mattress without lying on it for at least 10 minutes.
How much are we willing to pay for a good night's sleep? The range goes from €100 to over €1,000. But the real luxury may not be the price, but getting it right the first time.
