Fiber topper

Hypoallergenic fibres icons. It comprises a synthetic layer of hypoallergenic fibres inserts inside an outer cover of fabric, which is the majority of the seal of the case. This is the 100 100% machine washable option. However, it’s, in addition, the option that gives the lowest results when it comes to improving the comfort of the mattress. It utilizes by people who rest in memory foam beds without thermoregulatory treatments during the most scorching days of the year.

Viscoelastic topper

Viscoelastic icon. This is by far the most popular kind of mattress topper. It comprises a layer of thick typically about 3 to 6 centimetres high (depending on the requirements for additional adaptability for users of the mattress) that is inserted into a stretch cover. The covers that are usually removed with a zip generally have a summer-facing side that is upholstered with the breathable mesh fabric and a winter side to ensure better reception during the winter seasons. This kind of mattress is generally advised to people looking to ease the mattress’s firmness to make it more flexible and more comfortable. It’s also one of the most cost-effective and practical options.

Latex topper

Latex icon. It’s typically a kind of mattress protector that has a layer of latex in its other materials. The latex could be synthetic or Talley latex, which is more costly but more flexible, breathable, and long-lasting. The elements comprise a thick layer of hypoallergenic fibres that provide natural ventilation channels between sleeping and the bed. Air circulation is accessible at all times. They provide enough space between the sleeping person to the surface of the mattress in which air is circulated fluidly throughout the day. It suggests for older people because of the flexibility of changing positions it offers and for obese and extremely hot people who avoid the sensation of sinking into the mattress.

Down topper

A lot of people desire the feeling of softness and comfort on their mattress and not feeling overwhelmed. In all cases, the best option could be a mattress topper for down. The topper’s quality will be superior, depending on the recovery capacity of the core—also, the homogeneity of the distribution of fillings. To get the identical amount of down in every part at the top, distinct chambers are usually made and filled with equal material. This way, they prevent down accumulations in certain areas and the absence of padding in others. It’s a more significant expense than viscoelastic toppers. However, it benefits having less weight that allows for more accessible transport and storage when not required. It is, however, the best choice for those who are hot or sensitive to temperature fluctuations.

How to Cut Memory Foam Mattress Topper


Take off the cover if you cut your memory foam mattress. Many new memory foam mattresses come with an open cover that slides over to offer extra security. Find a zipper along the edges of the mattress, and then take it off. It is as far as you can. Once the zipper removes, please take off the mattress’s sliding edges and then remove it. When you’ve cut your mattress, you may throw it away or use the fabric to make an entirely new body. Either toss the cover away or make use of the material to construct the cover. If there’s no zipper on the edge of the deck, it is possible to cut it off using either a knife or a pair of scissors.


Determine the dimensions you require and then add these dimensions. Utilize a tape measure to measure the height, width, and depth of foam needed for your project. For instance, you can take measurements of a mattress when you cut out a memory foam top or locate the dimensions of a pillowcase when you are making an inflatable pillow. You can add to every measurement, as cutting through the foam could take away some foam.


The memory foam must mark using the permanent marker as well as the tape measure. Place the other end of your tape measure in the middle of the memory foam and take it off at the proper length. Make a dot in the memory foam using permanent markers after the action. Move the tape measure along towards the edges of your mattress. Then create a new mark that aligns with the original. Continue marking your memory foam till you get to the opposite side. Repeat the procedure for each of the dimensions you intend to cut.


Double-check the dimensions to be sure they’re accurate; otherwise, you could cut an unbalanced cut. Draw the lines of your stake on the foam using the help of a marker. Draw a straight line across to the foam to cross the marks you created to measure. Make use of a permanent marker to draw lines between the sizes to know where to make the cuts. The lines should be thinner so that your cuts and the dimensions are precise.


If you’re creating a curved line, use a round item to serve as a model, such as a coffee mug or a cup. Spread the foam out on a table so that the cut side hangs above the table’s edge. Choose a sturdy, flat plain to place your memory foam on. Place the memory foam on the table so the cut lines are in the direction of that of the table’s edges. This way, you don’t scratch the tabletop by cutting across the memory foam.


Set a heavy item on top of a sheet of memory foam to hold it in place if it lands on edge. Be sure that the object is not too far from the cut line so that the foam doesn’t shrink. Keep an electric blade parallel towards the memory foam. Plugin your electric cutting blade and then hold it in your hands. Make sure you position your knife so that your blade sits at a 90-degree angle to the cut edge to ensure straight, smooth cuts. Make sure that the edge of the ribbed trim meets with the memory foam and aligns with the lines you traced.


You can purchase an electric knife at any outlet in the kitchen or on. An electric blade will give the most precise cut. However, you can also use a knurled loaf knife if you don’t own an electric cutting knife. The knife must guide to follow the lines you pulled out of the foam. Switch on your electric knife and slowly follow the cursor’s line.

Be sure to place your knife at a horizontal position within the foam so that the cat doesn’t get bent. Be careful not to push the foam down during cutting, as it could warp, cutting incorrectly. Continue cutting the foam in the same direction till the whole length has been reduced. If you are required to remove it from foam, switch off the power before taking it out.


If you are using a bread knife with knurled blades, go back and forth to cut your slices. Repeat cutting along the line If the knife blade doesn’t go across the memory foam. If you have missed a large section of memory foam, your knife’s edge might not cut it completely. Place the blade that carve towards the end of the cutter, and follow the cut line.

Make sure that your cut remains straight and straight. Keep making cuts until the blade is entirely within the memory foam. Repeat the process for any other dimensions you have to cut through the memory foam. You can turn the piece of foam over to the opposite side and then retake your measurements. Slice the foam such that the two cuts are on the inside.

How to cut a memory foam mattress horizontally

If you want to reduce the thickness of your foam memory mattress to more slender, you can slice it horizontally. Let me warn you, now cutting a mattress horizontally can be pretty challenging. It requires precision, and obviously, special tools.

You have several options. The most commonly used is the long straight saw. Be sure to hold the top portion of the foam, but do not put too much pressure on it as you move the saw gently across the mattress. It is an excellent idea to place the mattress onto a sheet or towel since some foam pieces could fly about during the process. The mattress’s fabric will hold them and make the cleaning process much simpler for you.

Some suggest that it is possible to utilize the electrical saw when you own one. However, it can be risky, and I think it’s safer to stick with a traditional one. If you use the electric tool, it is possible to be hurt, particularly when you attempt to hold the upper part of the mattress to keep it from falling off when you cut. A standard saw is safer in this scenario.

Another alternative is a Hotwire (if you can find one large enough to fit your sleeping mattress). Remember that this option requires a more solid hand. It may also be more practical to remove the mattress when you put it on a higher base.


Who says you can’t cut a memory foam mattress topper? All you require is an adroit knife and a reliable ruler—also, a little sometimes. However, you’ll have almost any mattress size you’d like.
