1. Inspect
   Take memory foam lumbar cushion as example. Open the cushion case with zap, we can inspect the appearance of memory foam insert: it should smooth, soft. If we the insert if rough, with a lot of big bubble holes, the quality is not good. For the color the insert, it can be customized as yellow, black, red or any other color like normal foam. The natural color of memory foam insert should be white. After exposing in the open air, it will turn to yellow. Dremflavor’s memory foam lumbar cushion is with an anti-mite and moisture-proof inner cotton cushion case. Use a scissor to cut the case out so we can check out how it looks like.
2. Touch
   Take memory foam pillow as an example. We touch the pillow at the first time, cross the pillow case and press the memory foam insert gently, our pawl will feel the slowly, soft rebound. A good memory foam pillow should be same feeling in whole like the rebound time, the hardness. If the rebound time, the hardness is not the same, we can judge it a low quality.Memory foam product should be viscoelastic. When we touch Dremflavor’s memory foam insert, we will find it sticky and not wet skin feeling. This is real memory foam. Some manufacturers want to save production cost, so they use too much talcum powder, and lost the viscoelastic feeling, but get a dry, powder feeling surface instead.
3. Smell
   Top quality memory foam should be no odor no smell. Some manufacturers use a low end formula, or just use prohibited ingredients, which ended up with an unpleasant odor. The odor will be dissipated in the open air, until human nose can’t figure out. Actually the distribution is still existed, which is the potential harm to users’ health. The memory foam product from Dremflavor used new tech and formula, no smell even during the production, no potential harm. Dremflavor is going to update the technical and production skill—CFC. It is the best and environmental foam production technology. Some sellers even claim in the product page that if the product is no odor, it is not real memory foam. This is the biggest misleading of memory foam. They are not only will lost the confidence from customers, but also give themselves an excuse for law quality product.

Aboves are 3 methods to identify memory foam product quality. Dremflavor is also willing to share other 2 methods: 1. Put the foam into a refrigerator to check it whether get frozen. If it is frozen, it is not good quality. 2. Exposed under sunshine for a few days, if it is got aging, hard, or powdering, it is not a good memory foam product, too.
