How Much Does a Mattress Weigh: Weight by Size and Delivery Cost

The question "how much does a mattress weigh" is almost never really about weight. Behind it sits one of three practical questions: will I get it into the elevator and up the stairs, will the bed base take it and, most often of all, how much will shipping to another city cost. We will take them in order, because the answers are different.

What actually determines the weight of a mattress

Weight comes down to four things, and size is only one of them.

Surface area. The obvious one: 180×200 has exactly twice the surface of 90×200. All else being equal, weight doubles along with area.

Height. In the same construction, a mattress 24 cm high weighs roughly one and a half times as much as one 16 cm high, simply because there are more layers.

Fillings. This is the biggest multiplier, and the spread here is wider than anything size does:

• Polyurethane foam (PU foam) — the lightest of the main fillings.
• Latex — noticeably denser than PU foam; a layer of the same thickness weighs substantially more.
• Coconut coir — a dense, rigid board; it adds more weight than its thickness suggests.
• Thermo-bonded felt — a thin but dense separating layer, and a build usually has two of them.

The spring unit. Metal is heavy. An independent unit with 512 springs (MultiPocket) weighs more than one with 256 (PocketSpring) at the same size, because there are physically twice as many coils.

Which leads to something counterintuitive: a springless mattress is by no means always lighter than a sprung one. A springless model built on coir and latex can easily outweigh a sprung one built on PU foam in the same size. "Springless" is about the absence of metal, not about being light.

How to estimate the weight yourself

Only weighing a specific model gives you an exact figure, but the order of magnitude is easy to work out. Take the weight per square meter of your build and multiply it by the area (the standard size range):

• 90×200 — 1.8 m²
• 120×200 — 2.4 m²
• 140×200 — 2.8 m²
• 160×200 — 3.2 m²
• 180×200 — 3.6 m²
• 200×200 — 4.0 m²

So a 180×200 mattress, whatever the construction, will be exactly twice the weight of a 90×200 in the same materials at the same height. If you know what the single weighs, double it and you have the double.

For the exact weight of a particular model in the size you need, ask a manager. The factory has that figure, but it is different for every construction, and an averaged table would only mislead you here.

Why shipping is charged by volume, not kilograms

This is where we get to the reason the question usually gets asked in the first place.

Carriers price a shipment by volumetric weight, a figure taken from the dimensions rather than from the scales. And for mattresses the volumetric weight is almost always higher than the actual weight, because a mattress is a large box with very little density.

Let us run the numbers on real geometry. A 180×200 mattress 20 cm high works out to 1.8 × 2.0 × 0.2 = 0.72 m³. The same mattress in 90×200 is 0.36 m³, exactly half. The carrier takes the volume, converts it into a chargeable weight using its own coefficient, and bills you on whichever of the two figures is higher, actual or volumetric.

What that means in practice:

• Mattress height affects the shipping price more than you would expect. The gap between 18 and 24 cm is a third of the volume, and therefore a third of the freight cost.
• A sprung mattress cannot be rolled up. It ships flat and takes the full volume. Some carriers will accept springless PU foam models rolled, which cuts the volume several times over.
• A mattress topper and pillows add almost nothing to the same shipment. They are compact and the space is already paid for. If you are buying a set, send it as one item, not three.

Terms by region are collected on the delivery across Kazakhstan page. This is exactly why we never advertise "delivery from N tenge". The carrier calculates the amount from the specific model, size and city, and a manager tells you the figure before you pay, when the order is placed. In Almaty the question does not arise at all: our own courier delivers and carries the mattress right to your bed.

Will the bed base take it

The second practical question. Here it is important not to confuse two different loads:

• The weight of the mattress itself — a constant load on the slats and the frame.
• The maximum load per sleeping place — this one is about the weight of the sleeper, and it is listed in the specifications of every model on our product pages. How to match it is covered separately: what weight mattresses are rated for.

On an ordinary slatted bed, the weight of the mattress is never a problem. Two cases call for more care:

• A bed with a lift-up mechanism. The gas struts are matched to the weight of the mattress. Too heavy a mattress on weak struts and the base will not stay up; too light and it will spring open on its own. If you are switching to a heavier mattress, this is worth checking.
• A sofa bed. A thin topper and a full mattress are two different stories; a sofa mechanism is not designed for the constant weight of a full-size mattress.

Can I carry it myself

A mattress of 160×200 or larger is not a one-person job on a staircase, and it is less about the kilograms than the bulk: it is awkward to hold, it flexes and it catches on the railings. Use this as a guide:

• Up to 90×200 — one person can manage it.
• From 140×200 — you need two, whatever the filling.
• A narrow staircase, a turn on the landing, an elevator without freight dimensions — go by the width of the mattress, not the weight. A 180 cm mattress only fits into an 80 cm elevator on its edge, and not always then.

With delivery in Almaty the courier settles this question for you: he carries the mattress up and brings it to your bed.

Frequently asked questions

Which mattress size is the heaviest?

Of the standard sizes, 200×200: it has the largest area. But across different constructions, a 180×200 on coir and latex will easily come out heavier than a 200×200 on PU foam.

Is a springless mattress lighter than a sprung one?

Not necessarily. Spring metal is heavy, but the dense fillings, coconut coir and latex, are heavier than PU foam. Compare specific models, not types.

Does the weight of a mattress say anything about its quality?

Not directly. A heavy mattress usually means dense fillings or a high spring count, but "heavier" does not mean "better": choose by firmness to match your weight and sleeping position, not by the mass of the product. A separate question is how often you need to replace a mattress, and service life does not depend on weight either.

How much does a mattress weigh in its packaging?

Shipping packaging adds a little, but more to the point it increases the dimensions, and with them the volumetric weight the carrier bills on.

Do I need to know the weight to arrange delivery?

No. The manager only needs the model, the size and the city. They will work out the weight and volume themselves and quote you the amount before you pay.

Not sure which firmness is right for you? Tell a manager your weight, your partner’s weight and how you sleep, and we will pick the model and work out delivery to your city at the same time. Browse the mattress catalog or message us on WhatsApp, and we will reply during business hours.
