Size and Filling Guide

Bed sizes and fibre filling guide

Two things define a product: its size and the fibre inside it. This guide covers which fibre goes into which product and at what fill weight, then the textile sizes that match the bed sizes used in Türkiye.

Fibre First

Which fibre goes into which product?

Size gives a product its dimensions; fibre gives it its character. The table below lists the fibre types we produce, how each one feels and where it is used.

FibreFeelUsed in
Carded FibreDense-textured and economicalEconomy pillows, poufs and seat pad filling
Silicone Ball FibreClustered, springs back quickly after compressionPillows, cushions, poufs and decorative filling
Siliconised Fibre (HCS)Slippery-surfaced, holds its loft over timePillows and duvets
Microgel FibreThe softest option, with a down-like touchUpper-segment pillows and duvets
Hollow Conjugated FibreLight yet high in volumeWinter duvets and fillings that need loft
Flame-Retardant Fibre (FR)Standard feel with flame-retardant behaviourHotel, dormitory, hospital and public projects
Recycled Polyester FibreBehaves the same as standard polyesterProjects with sustainability targets

Fill Weight

How much filling gives which result?

These are the ranges we actually run on our line. Stating the fill weight alongside the size is enough for the product to come out the way you expect.

ProductFill rangeNote
Pillow650 – 1,200 gA soft touch sits near the lower end; a firm, full profile near the upper.
Duvet300 – 350 g/m²The all-season range. Summer weights go lower, winter weights higher.
Baby productsLightweight silicone fibreLightness comes first; sizes follow cot and travel-cot mattresses.

What to know when choosing fibre

  • Denier decides the softness

    Denier measures how fine a filament is. A low denier gives a fine, soft filling; a high denier gives a thicker, loftier and more resilient one. Changing denier alone changes how the product feels.

  • The silicone coating decides the recovery

    In siliconised fibre the filament surface carries a thin silicone layer, so filaments slide over each other instead of matting together. That is why the filling recovers its shape faster after compression.

  • Hotel and dormitory projects ask for flame-retardant fibre

    Buildings under fire regulations may require a flame-retardant (FR) filling. Share the project specification up front and we will select the right fibre and fabric together.

  • The same size at a different fill weight is a different product

    The size table gives dimensions, not character. A 195 × 215 cm duvet behaves as a summer duvet at 300 g/m² and a winter one at 350 g/m². State the fill weight alongside the size when you order.

Practical Rules

What to know when choosing a size

A calm bedroom seen from the doorway, the double bed made up in off-white bedding

  1. The cover should be 5 cm larger than the duvet

    The cover is cut a few centimetres larger so the duvet can move inside it. An exact-fit cover binds the duvet and leaves the corners empty.

  2. The duvet should overhang the mattress by 25–30 cm on each side

    This is why a 150 cm wide bed takes a 195–200 cm wide duvet. Without enough overhang the duvet pulls open during the night.

  3. The protector matches the mattress exactly

    Protectors and fitted sheets are chosen at mattress size; too large and they wrinkle, too small and the elastic slips off the corner. If your mattress is over 30 cm deep, state the side depth.

  4. Standard sizes vary between brands

    The values here are the most widely used sizes in Türkiye; there can be a few centimetres of difference between brands. Measure your mattress for a certain result.
