The plastic spikes are of moderate intensity and allow you to lie down for as long as you want without feeling discomfort. The height from the pillow is high, but because it is very soft, it compresses immediately, of course this has the following disadvantage, you lie down and the edges of the pillow fold and press on the ears which is quite unpleasant if you lie down for more than 10 minutes. The fabric has a very strong odor but with 2 days of airing in the sun it completely disappears. The inner sponge pad is of poor quality. After intensive use for two weeks, the pillow completely changed shape and does not return. If it had good quality in the inner filling-sponge-pad I would recommend it. If you want it for frequent use, like me, it is not of good quality.
