I agree - white luxury bedding and perhaps change the lampshades.

You have a lovely room, but the grey/black overpowers the space and is very very cold. However on the upside its easy to work with so if you dont want to change the main bed linen then try adding some warm colours in a throw rug and cushions (eg mustard/gold cushions and matching throw) that contrast well with the grey/black/white scheme and especially in a textured/knitted or warm fabric (eg velvet). Replace the black shades with something lighter colour and Id definitely replace the black square european cushions with white ones and soften the window by installing a white, sheer fabric floor-drop curtain.

Alternatively, if you want to keep it monochrome then timber also adds warmth, so if you can find some antique style timber bedsides in a warm walnut colour it would also make a huge difference but at the same time work perfectly with the colours you already have and your pendant light - but Id still replace the black pillows and shades with white.

would say adding mustard help...

The bedhead is nice, but everything else emits a cold, clinical vibe. A sheer curtain from the ceiling and pulled across the blind would soften the space. i find the black chandelier quite overpowering too. at the end of the day it comes down to personal taste and if it is your bedroom, it should be decorated in a way that you find restful. As a guest room - simple square timber bedside drawers in a teak finish, less fussy lamps and crisp white linen would create a welcome ambience for visitors.

Why is everything so white or grey these days in Australia. Europe has moved on, take a look at the examples below. They are not necessarily bedrooms, but COLOUR! Some are fabric ideas.

When re-decorating a Spare Room, it is interesting to have it looking quite different to the other rooms in the house, as usually the door is closed; so when someone arrives to stay or you want to breath in a different scene, it is great to surprise.

Keeping abreast of interior movements is paramount, as we don't want to re-decorate too often, especially for a Spare Room.

(1) I love the idea of a sumptuous fur at the end of the bed.

2) Fairly crazy pattern, but interesting colour scheme, especially walls and trims.

(3) I have used this fabric on a couple of occasions, it works extremely well just as sham pillow covers and adds interest to quiet colours.

(4) Luscious, with modern touches and (6 restful).

(5) Below is a collection of co-ordinating rich fabrics which would go well with your existing decor, giving an updated influence.

(6) This image above was meant to be placed at the base, as it is quite static, but I was unable to remove it. Just learning the process.

If you are determined to keep the bedding in place, I would bring your white pillows into the mix in front of the European pillows and add a burgundy velvet throw underneath the grey throw for an extra layer of texture. And I would arrange the smaller cushions as in the picture to allow them to breathe yet still blend in.

I would also untuck the bedding to allow it to flow down the sides of the bed for a luxurious look.

Adding some curtains across the window as suggested will also add a layer of softness to the room.

Adding mustard will give the room a softer more casual vibe to your space.

Pair with blush pinks to tie the space together.
