Where to Find Oversized Mattresses

Most companies do not manufacture oversized mattresses. Those who need them place a custom order at companies or specialized boutiques that sell beds and mattresses personalized to your sleep needs and preferences like mattress thickness or filling.

Oversized mattresses are larger than the standard mattress sizes. For example, an Emperor that measures 215 x 215cm (7ft by 7ft). Two or more sleepers who need large sleeping space to spread out need oversized mattresses.

The drawback is it is difficult to move such a massive bed. Hence, they have less demand and are not easily available in the market.

Customized beds are more expensive than ready-made beds. Check out if your preferred bed and accessories are all available within your set budget.
