In Argentina, mattress sizes generally follow specific standards that are somewhat different from international sizes. Here are the common mattress sizes in Argentina:

- Individual (Twin): 80 cm x 190 cm

- Una Plaza (Single): 100 cm x 190 cm

- Dos Plazas (Double): 140 cm x 190 cm

- Matrimonial (Queen): 160 cm x 200 cm

- King: 180 cm x 200 cm

- Super King: 200 cm x 200 cm

These sizes are approximate and can vary slightly between manufacturers. It's always a good idea to check the specific dimensions provided by the manufacturer or retailer when purchasing a mattress. Additionally, some retailers may offer custom sizes to fit specific needs or bed frames.

In Argentina, mattresses are often measured in centimeters, so it's important to double-check the dimensions to ensure the mattress fits your bed frame properly.
