The Sizes Available for OSleep Firm Mattresses
King-Size Mattresses

If you are someone who likes having loads of room in your bed, you will want to look at a king-size mattress. These mattresses are great for master bedrooms and measure 76" X 80". They are perfect for couples, offering extra space for you to move around. Something to keep in mind is that they are heavy and large, making them difficult to transport and flip. Also, king-size mattresses are not suitable for areas with limited room, since they can make the area look even smaller.

Full-Size Mattresses

If you want a full-size mattress, the comfortable OSleep firm mattress might be right for you. These mattresses are perfect for couples, offering a closer fit between the two sleepers. They fit in studio apartments and measure 54" X 75". However, they are short in length, so they might not be a good option if you're 6'3" or taller. Another downside is that they have a narrow width, which makes them less than ideal for those who enjoy having extra space while sleeping.

Twin-Size Mattresses

If you want a twin-size mattress, the comfortable OSleep firm mattress might be right for you. Twin-size mattresses can be easily transported because of their compact build. They are perfect for children's rooms and guest rooms and measure 39" X 75". They are spacious enough for one person without taking up as much room as a queen-size mattress. They are constructed to save space, leaving plenty more room for other decorations in narrow bedrooms. However, these mattresses are short in length, so they might not be a suitable option if you're taller than 6'3". In addition, they are too small for two people to sleep on, so they're not ideal for people who share their bed.
