Q : I have seen the Holbein mattress in Costco. It looks
excellent value but difficult to test. Looking for a medium rather
than firm. Also is it a standard uk double its to go into a bed
frame with solid slats. If not suitable which would be.


A : Comfort is very subjective. We would say the Holbein as a
medium-firm feel, the mattress will feel more firm if placed on a
solid base.It is worth stating something about the minimum 'grade'
of slats on a slatted base. Wood slats-slats should be smooth,
preferably with chamfered edges to prevent cut through to the
mattress underside-maximum space between slats should be no more
than 100mm-minimum width of slats should be approx. 70mm-the entire
length of the mattress should be supported by slats, i.e.. slat
ladder length should be same mattress.-slats should be secured to
bedstead properly to prevent movement of slatsBelow is a breakdown
of the different sizes and their approximate imperial
equivalents:Single 90cm x 190cm - approx. 3'0" x 6'3"Double 135cm x
190cm - approx. 4'6" x 6'3"King Size 150cm x 200cm - approx. 5'0" x
