Step 1 of 6

##  Mechanism
 The opening action decides floor space — measure the room with the bed fully open.

  Mechanism         Click-clack / futon    Back folds flat
-        Pull-out / slider    Drawer or slide bed
-        Trundle / guest roll-out    Second mattress rolls out

##  UK size
 Open sleep size is what matters — closed sofa width can look smaller than the open mattress.

  UK size         Single · 90 × 190 cm    One sleeper
-        Double · 135 × 190 cm    Couples — tighter width
-        King · 150 × 200 cm    Common couple size

##  Storage
 Guest beds prioritise open footprint over deep bedroom storage.

  Storage         No extra storage    Mechanism only
-        Chaise / side storage    If the model allows

##  Fabric family
 Fabric is visual and care behaviour. It does not set spring tension or foam density.

  Fabric family         Plush velvet    Even pile, richer sheen
-        Crushed velvet    Mottled sheen
-        Chenille    Soft, matte-to-warm feel
-        Linen-look weave    Flatter, textured cloth
-        Faux leather    Wipe-clean face

##  Colour language
 These are common UK shop colour words — useful for literacy, not a paint formula.

  Colour language         Cream    Warm light neutral
-        Mink    Warm taupe-grey
-        Charcoal    Deep cool grey
-        Silver    Cool light grey
-        Royal blue    Deep accent blue
-        Forest green    Deep green accent

##  Mattress class
 Match foam or pocket type to occasional use — then set guest duvet TOG.

  Mattress class         Reflex / guest foam    Common on sofa beds
-        Thin pocket unit    If the mechanism allows
-        Guest hybrid topper stack    Comfort layer add-on
