FAQs

Q: What is the largest size mattress?

The biggest mattress available is the Alaskan King, measuring a massive 9 feet by 9 feet (108 inches by 108 inches)! It’s perfect if you love plenty of space to stretch out or if you want room for the whole family to snuggle in comfortably.

 

Q: What mattress is best for a tall person?

If you’re tall and tired of your feet dangling off the bed, we’ve got you covered! The California King is a great option with extra length, measuring 72 inches wide by 84 inches long. For even more space, consider the Wyoming King (84 inches by 84 inches) or go all out with the Alaskan King (108 inches by 108 inches) so you can sleep in complete comfort.

Q: Are there huge beds made for a whole family?

Absolutely! There are oversized beds like the Alaskan King and the Family Bed designed specifically for families who love to share sleeping space. These giant mattresses offer plenty of room for everyone to sleep comfortably without feeling cramped.

Q: What size is an RV King mattress?

An RV King mattress typically measures 72 inches wide by 80 inches long, which is slightly narrower than a standard King mattress that is 76 inches wide by 80 inches long. However, sizes can vary between manufacturers and RV models, so it’s a good idea to measure your specific bed frame to ensure a perfect fit.

Q: Can you put a regular king mattress in an RV?

While it’s possible in some larger RVs, putting a regular King mattress (76 inches wide by 80 inches long) into an RV can be challenging. Standard mattresses are often heavier and less flexible, making them difficult to maneuver through the narrow doors and tight spaces of an RV. Additionally, the extra width might not fit the designated sleeping area, potentially obstructing walkways or cabinets.

Q: How is an RV mattress different?

RV mattresses are specifically designed to fit the unique space constraints of recreational vehicles. They often have different dimensions compared to standard mattresses to accommodate smaller or irregularly shaped sleeping areas. RV mattresses are also typically lighter in weight to avoid adding unnecessary load to the vehicle, and they may be constructed with materials suited for varying climates and travel conditions.

Q: Is there an RV with a king size bed?

Yes, many larger RVs, fifth wheels, and motorhomes come equipped with a king-size bed or offer it as an upgrade option. These RVs are designed with enough space to accommodate a king-size sleeping area, providing you with the luxury and comfort of a spacious bed while you’re on the road.

Q: How thick should an RV mattress be?

The ideal thickness for an RV mattress usually ranges from 6 to 10 inches. The appropriate thickness depends on your comfort preferences and the space available in your RV. Thicker mattresses offer more cushioning but may reduce headroom or interfere with overhead storage. Always measure the vertical space to ensure the mattress thickness won’t cause any issues.

Q: Will regular king sheets fit an RV King?

Regular King sheets are designed for mattresses that are 76 inches wide, while an RV King mattress is typically 72 inches wide. This means standard King sheets may be a bit loose on an RV King mattress. For a better fit, you might consider using RV-specific king sheets or adjustable sheets that can accommodate the slightly smaller dimensions of an RV King mattress.
