Goodside 3in1 is the name for a bed base made of glass-fibre reinforced plastic slats that perfectly cushion the body all over and prevent it from sinking too far into the mattress. Irrespective of body shape, the back is well supported in any position. The materials used ensure durability and consistent elasticity. The slats are available in various hardness ratings which are characterised by different colours. Depending on the arrangement, the user can choose between a strong, medium or soft hardness rating.
