How to choose a mattress: firmness, load and height
· updated
Choosing a mattress comes down to three parameters: firmness, which is matched to body weight; maximum load, a separate specification that is often confused with firmness; and the type of core — a spring unit or a solid foam core. Everything else — the fabric, the height, the name of the line — affects comfort and price, but not whether the mattress actually suits you.
Below we go through each parameter using the figures from our own catalogue: 46 models made at our factory, each with firmness, maximum load, layer composition and height listed on its product page. We are a factory, not a shop, so we can show the whole range at once — including things that are not in our interest to sell.
Firmness is matched to weight, not to how it feels in the shop
Go by the weight of the person who sleeps on that side, not the average weight of the couple:
- up to 60 kg — soft or medium-firm;
- 60–90 kg — medium-firm;
- over 90 kg — firm, or a 512-spring unit.
The logic is simple: under a light person a firm mattress does not give at all, and the lower back is left without support. Under a heavy person a soft mattress sinks right down to the base and turns into a hammock.
Firmness comes not from the springs but from the layers on top of them. Coconut coir adds firmness: Hard M has two 3 cm layers of it, which makes it the firmest model in the range. Latex and PU foam add softness. That is why some models have two different sides — coir on one, latex on the other — and you can flip the mattress if your first guess was wrong.
The catalogue has four soft models (Comfort P, Comfort M, Memory P, Memory M) and ten firm ones (Hard P, Hard M, Mega P, Mega M, Mix P, Olymp P, Olymp M, Imperial P, Imperial M, Sandwich Cocos/Latex). The rest are medium-firm, and that is not caution on the manufacturer's part: it is what most people need.
Maximum load is not the same as firmness
This is the most common mistake. Firmness is about feel; load is about how many kilograms the construction carries per sleeping place without sagging before its time. What else shortens a mattress's life is covered in how long a mattress lasts.
Here is how the 45 catalogue models with a stated load are distributed:
| Load | Models | Examples |
|---|---|---|
| up to 100 kg | 4 | Balance F, Green Line F, White Star F, Transformer F |
| up to 110 kg | 1 | Diamond F |
| up to 115 kg | 4 | Standart P, Optima P, Comfort P, Transformer P |
| up to 120 kg | 20 | Seasons P, Stem P, Organic P, Aura P, King L, Rich L |
| up to 140 kg | 10 | Seasons M, Stem M, Organic M, Comfort M, Memory M, Latex Solid |
| up to 150 kg | 5 | Hard P, Mega M, Mix P, Imperial M, Sandwich Cocos/Latex |
| up to 170 kg | 1 | Hard M |
Two things only become visible in a table like this.
Soft does not mean "for light people". Comfort M and Memory M are soft models, and both carry 140 kg. The softness comes from the top layer; the load is carried by the 512-spring unit underneath.
From 150 kg the choice narrows sharply. Five models carry 150 kg and one, Hard M, carries 170 kg. Nothing in the catalogue goes above 170 kg. If your weight is close to that limit, go straight to this short list instead of browsing the whole catalogue.
Tall and expensive does not mean durable
This is something that usually goes unsaid.
The six tallest mattresses in the range are Rich L (38 cm), Premium L (37 cm), King L (36 cm), Lux L (35 cm), Gold L (34 cm) and Diamond L (33 cm). They sit at the top of the price list: 161,100–220,800 ₸ for 160×200. All six are rated for 120 kg.
For comparison, Hard M — 22 cm tall and 134,000 ₸ for the same size — carries 170 kg.
So for 86,800 ₸ more you get more layers, a more elaborate surface and a feeling of depth, but a smaller load margin. Height grows through comfort layers — memory foam, latex, extra coir — not through load-bearing capacity. The load is still carried by the spring unit.
The practical conclusion: if weight is your main criterion, height and price will not help you — look at the "maximum load" line. If your weight is within range and you want something softer and deeper, then height gives you exactly what you are paying for.
Springs or a solid core
The catalogue has four types of core: PocketSpring 256 (22 models), 512-spring units (11 — ten MultiPocket 512 and one PocketSpring 512), PU foam (8) and solid slabs — Foam and 100% latex (4).
PocketSpring 256 — independent springs, each in its own pocket. Point support, no motion transfer to the other half, good ventilation. The basic and most popular option.
MultiPocket 512 — twice as many springs over the same area, so the unit follows the body contour more closely. The difference shows in two cases: at higher body weight and when partners weigh very differently. It is no coincidence that all eleven 512-spring models carry 140 kg or more — the only group in the catalogue without a single exception.
Springless does not mean "cheap" or "soft". Sandwich Cocos/Latex is springless, firm, carries 150 kg and costs 245,700 ₸ for 160×200. Latex Solid, made of solid latex and only 13 cm tall, carries 140 kg. "No springs" means no metal inside, and nothing more.
If you sleep as a couple
Three rules cover most questions.
Count the load by the heavier partner — it is stated per sleeping place, not for two people combined. If the partners weigh 70 and 95 kg, go by 95.
If the weight difference is more than 25–30 kg, choose 512 springs. On a 256-spring unit the heavier partner presses their zone down harder, and the other rolls towards the middle. A 512-spring unit keeps the dip local.
Choose firmness by the heavier partner and let a mattress topper make up the difference for the lighter one — it costs less than getting the mattress wrong.
What it costs
According to the catalogue in September 2026: 160×200 — from 63,400 to 474,900 ₸, 80×200 — from 30,500 to 216,800 ₸. The spread is roughly sevenfold, and it comes from three things: fillings (natural latex and coir cost more than PU foam), height and number of layers, and the type of spring unit.
What a higher price does not buy you is a higher maximum load. The table above shows it, and it is worth remembering when talking to any seller, not only us.
What not to do
Rely on the "orthopedic properties" line. It appears on product pages, but it is a rating scale ("medium", "above average"), not a measured value. Go by load, firmness and layer composition — those are facts.
Buy the firmest mattress "for your back". A firm mattress is needed for higher body weight, not for pain as such. If your back hurts regularly, the mattress is chosen after seeing a doctor, not instead of it.
Treat height as a sign of quality. See above: the six tallest models in the catalogue are the most expensive and not the most durable.
Buy without trying, if you have the chance to try. Fifteen minutes in the showroom tell you more than any article, including this one.
In short
- Firmness — by the weight of the person on that side: up to 60 kg soft or medium, 60–90 medium, over 90 firm.
- Maximum load is a separate parameter, stated per sleeping place. Five models carry 150 kg, one carries 170 kg, and nothing goes higher.
- Height and price do not increase load: all six models 33–38 cm tall are rated for 120 kg, while Hard M at 22 cm carries 170.
- 512 springs make sense at higher weight and when partners weigh very differently.
- Springless does not mean soft or cheap.
Every model, with its load, firmness and layers, is in the mattress catalogue. Not sure which to choose? Tell a manager your weight, your partner's weight and how you sleep. Those three numbers are enough to narrow the choice down in a minute.
