The present invention relates to a pillow having a thin envelope layer adjacent a bottom surface isolated from the top surface of the pillow by compressible filler material. It has been found that this thin envelope layer filled with a suitable fluid with the compressible filler thereabove greatly improves the comfort of the pillow and the size of the envelope can be reduced. By so positioning the envelope, the range of deformation and orientation of the envelope is reduced.
