Find the mattress that fits you

A King mattress in Qatar is 180 × 200 cm, not the 193 × 203 cm sold as a King in the United States. Qatar and the wider Gulf use European metric dimensions with American size names, which is why the same word means different beds in different countries. The common Qatar sizes are Single 90 × 190, Double 140 × 200, Queen 160 × 200 (sometimes 150 × 200), King 180 × 200, and Super King 200 × 200. Some retailers do stock the American 193 × 203, usually labelled American King. Always check the centimetres against your bed frame rather than trusting the name.

Side sleepers generally do best between 4 and 6 out of 10 — medium-soft to medium. Sleeping on your side concentrates your body weight onto the shoulder and the hip, so the surface has to compress enough at those two points to keep your spine roughly horizontal. Body weight shifts this: under 60 kg, aim a point softer; over 90 kg, aim a point or two firmer, because a heavier body compresses the same mattress more deeply.

Probably less than the advertising suggests, if your bedroom is air conditioned overnight. Research links good sleep to a bedroom temperature of roughly 15.6 to 20 °C, and a typical air-conditioned Doha bedroom already sits in that range — surveys across the Gulf find more than 35 per cent of occupants report being uncomfortably cold indoors, not hot. Cooling features genuinely matter in narrower cases: bedrooms without air conditioning or where it is switched off overnight, ground-floor and majlis rooms with poor cooling, menopause and other physiological causes of night sweats, and summer power cuts when outdoor temperatures reach 41 °C. Separately, gel infusions are weak evidence: gel adds a finite amount of thermal mass that absorbs heat for roughly 30 to 90 minutes and then saturates. Consumer Reports and Sleep Foundation testing both found gel foam performing comparably to standard memory foam. Airflow through a coil layer removes heat far more effectively than any infusion.

Most mattresses last between 7 and 10 years, with latex often lasting longer and low-density foam considerably less. Foam density is the most useful durability specification and the one brands are least likely to publish: polyfoam should be at least 1.8 lb per cubic foot (29 kg/m³) and memory foam at least 4.0 lb per cubic foot (64 kg/m³). Non-disclosure of density is itself a signal. Thickness is not a quality indicator — Consumer Reports lists it among common mattress misconceptions, and brands routinely inflate height with low-density filler. Replace based on how the mattress performs rather than its age: visible sagging, waking up sore, or sleeping better away from home are the signals that matter.
