What decides the choice

A mattress is one of the few purchases you use every night for years, yet many people choose one in two minutes of sitting on its edge in a showroom. Three questions shorten the path: how do you usually sleep, on your side, back or stomach? Do you sleep alone or with a partner who moves a lot? And do you feel hot at night?

The Sleep Foundation explains that firmness is usually described on a 1 to 10 scale, that side sleepers tend to prefer more give at the shoulder and hip, that back and stomach sleepers tend to prefer medium-firm or firmer so the hips do not sink too far, and that body weight changes the feel: a heavier person feels the same mattress as softer. For people who change position often, medium firmness is the most versatile. This is a starting point, not a prescription; comfort is personal in the end.

The practical types

What really separates one mattress from another

• Size in centimetres. Names such as "queen" and "king" differ between markets and brands. Measure the inside of the bed frame in centimetres and compare it with the mattress's stated dimensions.
• Thickness and bed height. A thick mattress on a high frame can make getting up harder for older people and may not fit your current sheets.
• Edges. If you sit on the side of the bed or share it, ask about edge support so you do not feel you are sliding off.
• Heat. In a Saudi summer, ask about the cover fabric and how the layers breathe, and remember that a protector can trap heat too.
• Foam certification. A certification such as CertiPUR-US covers the polyurethane foam inside the mattress for certain substances and emissions; it does not cover the whole mattress or prove comfort or durability. Read it for what it is.
• The word "medical". You will see «طبية» (medical) on many mattresses in the Saudi market; it is usually a marketing description, not a common specification, and does not mean a set firmness. Ask for the actual firmness on the scale and the layer types instead of relying on the name. If you have a back or joint condition, ask your doctor rather than the seller's description.
• The base. Some makers require a particular base or a maximum gap between slats for the warranty to apply. Read that condition before buying.

Trial, returns and warranty

Consumer Reports notes that many brands selling online offer trial periods from a month up to a year, but some charge transport or restocking fees, some require you to sleep on the mattress for a minimum period before a return, and a store's policy can differ from the maker's. In Saudi Arabia, read the written terms of the exact seller you are buying from:

• Can it be returned once unwrapped? Who pays for transport?
• Is the refund in cash or store credit?
• What exactly does the warranty mean: how many centimetres of sag count as a defect, and is a mattress protector required?

Delivery and getting it into the room

A mattress rolled in a box passes easily up stairs and in lifts, but it needs hours to reach its full shape and may smell at first, so it needs a ventilated room. A large traditional mattress may not pass a narrow stair or a tight corner, so measure the path from the door to the room before delivery day, and ask whether delivery includes setting it up and taking the old mattress away.

Common mistakes

• Judging a mattress from a short sit on its edge. Lie on it in your usual sleeping position for several minutes if you can.
• Buying the firmest one on the assumption it is best for everyone.
• Ignoring the trial conditions until the return window has passed.
• Putting a new mattress on an old, sagging base.
• Forgetting to measure the bed in centimetres and relying on the size name.

Before you pay

• Decide your sleeping position and who shares the bed, then set the firmness range you will look in.
• Measure the bed and the route to the room.
• Read the trial, return and warranty terms in writing from the seller itself.
• Compare listings on the Products page and look for a code on the Codes page.
