If you own a sofa bed, you’ve probably wondered whether you need a separate mattress or if the built‑in cushion is enough. The short answer: most sofa beds perform best with a dedicated mattress, especially if you use them for regular sleep. A proper mattress adds support, comfort, and durability, turning your couch‑by‑day into a decent bed by night.
A sofa bed’s frame is designed to fold, so the cushion you sit on usually isn’t thick enough for a full night’s rest. Without a mattress, you’ll feel the springs or slats underneath, which can lead to aches and a restless night. A mattress also spreads your weight evenly, reducing pressure points on the hips, shoulders and back. This is key if you share the sofa bed with guests or use it weekly – the extra comfort can keep the piece looking and feeling good for years.
Another benefit is hygiene. A removable mattress can be flipped or rotated, letting you air it out and clean it more easily than a built‑in foam layer. If you ever need to replace it, buying a mattress is simpler and often cheaper than swapping the whole sofa‑bed mechanism.
Start by measuring the sleeping surface. Most sofa beds have a standard size of 72‑78 cm wide and 180‑200 cm long, but measurements vary. Write down the exact width, length, and thickness the frame can hide. Most manufacturers recommend a mattress no thicker than 10‑12 cm so the frame folds smoothly.
Next, think about material. Memory foam is popular because it conforms to the body and stays thin. Latex offers bounce and breathability, while pocket‑spring models give a more traditional feel. If you want a budget option, a high‑density foam mattress works well and keeps the price low.
Don’t forget the cover. A removable, washable cover protects against spills and dust, which is useful in a living‑room setting. Some covers are made from breathable fabrics that keep the mattress cool, useful if the room gets warm at night.
Finally, test comfort before buying. Many online shops let you try the mattress for 30 days with free returns. If you can, sit on it in the showroom and lay down for a minute – you should feel supported but not too firm.
Putting it all together, a good mattress makes your sofa bed a reliable sleep spot, boosts durability and keeps your living area tidy. Measure, pick the right material, and watch for a washable cover, and you’ll get the most out of your convertible couch without breaking the bank.
