People have various aesthetic visions and perceptions. A rectangular mattress may look ho-hum to your otherwise eclectic taste in interior design. If you can't find the right mattress shape for you, why not get a foam mattress with the right comfort in it and shape it up to any shape you want. One good example is to have it shaped like a circle or an oval.
Step 1: Choose your foam and your bed frame. You can have a carpenter design you a circular bed friend and you can pattern the size of your mattress from there. After choosing the bed frame, you can now find a good size of foam. Make sure you follow the rules in picking a foam. It should have the right density in it. The mattress should also be thick enough to provide comfort. Aesthetics has to mingle with support when it comes to sleep preferences, don't you think?
Step 2: Prepare the materials. Get your foam, scissors, sharp knife, markers and measuring tape. Measure the foam first and find out the desired size. If you want, you can cut out a pattern first using Manila paper and marker to make the size a lot more precise and then lay it over the foam push a pin needles on top of it and then use the marker to mark the edges of the pattern.
Step 3: Remove the pattern and the needles that secure it and then start cutting the foam to the patterned shape using the knife. If your knife is sharp enough, it should cut the foam easily.
Step 4: Now you can make a customized cover for your foam. Use the Manila paper pattern and place it on top of the fabric. Secure the edges with pins again. Trace the manila paper on the fabric with a pencil or a washable marker.
Step 5: Do one more so you have a pattern for the top and bottom of the foam mattress. Afterwards, measure the circumference of the round foam and then measure the height. Using the measurements, make a pattern out of it. Cut the fabric but leave an inch of allowance for the sewing part.
Step 6: now assemble the cover. Sew the edges carefully. One side should be left open for zipper. Sew zipper to the one side of the cover. Once you are done, cover the circular foam with it.
