The Malm bed from IKEA fits standard queen-size bed sheets, which are typically 60 inches by 80 inches. When selecting bed sheets for the Malm bed, make sure to choose queen-size sheets to ensure a proper fit. Additionally, deep-pocket sheets may be necessary if the mattress on the Malm bed is thicker than average. It is recommended to measure the mattress height before purchasing bed sheets to ensure they will fit properly. **

To remove dried blood from a white bed sheet, you can start by soaking the stained area in cold water for about 15 minutes. Then, gently rub the stained area with a mixture of cold water and a small amount of laundry detergent or enzyme-based stain remover. After that, wash the bed sheet in cold water with regular laundry detergent. If the stain persists, you can try using hydrogen peroxide or a paste made of baking soda and water to spot treat the area before washing again. Always check the care label on the bed sheet for any specific instructions. **

A non-slip bed sheet is a type of bedding that is designed to stay in place on the mattress without shifting or bunching up. These sheets are typically made with special materials or features that help them grip the mattress surface, preventing them from sliding around during sleep. Non-slip bed sheets are especially useful for people who move around a lot during the night or for those with adjustable beds, as they help to keep the bedding in place for a more comfortable and secure sleep experience. **

Cold water alone may not be enough to completely remove a blood stain from a bed sheet. While cold water can help to initially dilute and rinse away the blood, it may not be effective at breaking down and removing the proteins in the blood that cause the stain. For best results, it is recommended to use a combination of cold water and a stain remover or enzyme-based cleaner specifically designed to break down and remove blood stains. **

The spot on the bed sheet appears to be a small stain, possibly from spilled food or drink, body oils, or makeup. It could also be a result of a small tear or damage to the fabric. It's important to address the stain promptly to prevent it from setting and becoming more difficult to remove. Using a stain remover and laundering the sheet according to the care instructions should help to remove the spot. **

A gel pen or a ballpoint pen would write best on a bed sheet. These types of pens have a smooth and consistent ink flow, which allows them to write effectively on fabric surfaces. Additionally, they are less likely to bleed or smudge on the fabric, making them a good choice for writing on a bed sheet. **

To determine which bed sheet to buy, consider the size of your mattress (twin, full, queen, king), the depth of the mattress, and your personal preferences for material and style. Measure the depth of your mattress to ensure the fitted sheet will fit properly. Consider the material - cotton is breathable and easy to care for, while silk is luxurious and smooth. Finally, choose a style and color that complements your bedroom decor. **

To remove blood stains from a bed sheet without taking it off, you can start by blotting the stain with a clean cloth or paper towel to absorb as much of the blood as possible. Then, mix a solution of cold water and a small amount of mild detergent, and gently dab the stain with the solution using a clean cloth. Continue blotting and dabbing until the stain starts to lift. You can also try using hydrogen peroxide or a paste made of baking soda and water to help remove the stain. Once the stain is gone, let the area air dry or use a hairdryer on a low setting to dry the spot. **
