A 180x200 cm mattress provides two people with one continuous sleeping surface for a double bed. However, the large surface area alone says little about actual sleeping comfort. Factors such as the core construction, firmness, ventilation, cover and suitability for your bed slats are also important.
If you focus only on the height or a marketing term such as ‘orthopaedic mattress’, you may overlook important details. This selection guide explains which specifications you should check before buying and which models may suit different requirements.
Specifications such as H2, H3 or H2/H3 are useful as a guide, but they are not part of a standardised measurement scale across countries. Body weight, body shape, sleeping position and personal comfort preferences all significantly affect how firmness is perceived. Depending on its construction, an H3 mattress may feel different from another model with the same rating.
For couples, there is an additional consideration: one shared mattress must suit both people. Reversible models with two firmness levels can be a practical option, but they do not replace a careful review of the product specifications.
A 7-zone mattress divides the sleeping surface into areas with different properties. This can be relevant for side, back and front sleepers. However, the zoning should suit your height and sleeping position. If the zoning is too short or positioned incorrectly, your shoulders and hips may not be located where the mattress construction provides a different level of give.
Having a mattress delivered rolled up makes it easier to transport through narrow stairwells and hallways. However, after unpacking, the core needs time to regain its intended shape. Depending on the model, 24 to 72 hours may be recommended. Open the packaging carefully, as sharp objects can damage the cover or core.
A 180x200 cold foam mattress consists of an open-cell foam core. Important factors include the foam density, core height, profiling and whether both sides can be used. A taller mattress is not automatically more durable, but it can make getting in and out of bed easier.
A 180x200 pocket sprung mattress uses individually encased springs. These respond independently and can limit movement across the sleeping surface. A 180x200 hybrid mattress often combines pocket springs with layers of foam. For couples, motion transfer is therefore an important point of comparison.
Do not compare only H2 or H3; also check the stated maximum load. For two people, the permitted total load should provide sufficient leeway. Statements such as ‘suitable for heavier people’ should only be taken into account when a specific weight limit is provided in kilograms.
A breathable mattress can support air circulation within the sleep system. However, the bed slats, room climate, duvet and mattress protector also affect moisture regulation. For allergy sufferers, a mattress with a washable cover is particularly practical. Look for:
A cover that can be washed at 60 °C can make regular cleaning easier. The foam or spring core itself must not usually be washed.
Why this product suits the profile: According to the product details, this reversible 20 cm cold foam mattress offers both H2 and H3 firmness levels in one model. This may appeal to couples who prefer different levels of firmness.
Rather than offering only one firmness option, the mattress can be turned over. The cover has a full-length zip and can be removed; according to the product details, it is washable at up to 60 °C.
7 zones, 20 cm height, fabric turning handles and rolled delivery. Stated maximum load: 200 kg.
Why this product suits the profile: The combination of cold foam and 868 individually encased pocket springs is aimed at buyers who want to compare several technical features in one mattress.
The product details provide specific figures for the core, height, number of springs, load capacity and delivery format. The term ‘orthopaedic’ should be understood as a product description, not as a medical promise.
7-zone pocket spring core, H3, 20 cm height, four handles and an anti-slip underside. Stated maximum load: 280 kg.
Why this product suits the profile: This 24 cm high hybrid mattress combines five zones with individually encased springs, reinforced edges and a knitted cover. It suits couples who regularly use the entire sleeping surface.
The reinforced edges address the often-overlooked edge area. Rolled delivery can make it easier to transport the mattress through narrow stairwells and hallways in the UK.
5-zone pocket springs, H2/H3 specification, reinforced edges and a breathable knitted cover. Allow 48 to 72 hours for the mattress to fully expand.
Why this product suits the profile: The individually encased pocket springs and reinforced edges are designed for two people and consistent use of the sleeping surface.
The specifications explicitly mention the spring construction and motion isolation, rather than making only general claims about ‘undisturbed sleep’. According to the description, the cover is not intended for machine washing.
Four-layer construction, H2/3, five zones, reinforced edges and rolled delivery. According to the product details, care involves spot cleaning.

This depends on the model. A period of 24 to 72 hours is often specified. The mattress should be fully unrolled on a suitable bed frame and left to air in a well-ventilated room. The information on the product label and in the instructions for use is decisive.
Its lifespan depends on the core material, load, support system, room climate and care. Turning the mattress regularly can help ensure more even wear, provided this is recommended by the manufacturer. A washable cover supports good hygiene, but it does not automatically extend the structural lifespan of the mattress core.
Neither H2 nor H3 is universally suitable for every double bed. Consider your body weight, height, sleeping position and preferred level of firmness. If you have different preferences, a reversible H2/H3 mattress or a model with two separate mattresses may be the more suitable choice.
