Go to thecompanystore.com to look at their brown and tan bedding. Note that the light browns in the inspiration photo match the platform bed to get the effect.

Take this photo and go to a good department store like Macy's and any good sales person can help you get the right pieces . I do however temper that advice with practicality . Honestly is this how you want your bed to look? IMO pretty messy and too nay pillows thta need to be moved to go to bed and not really practical for most guys I know. IMO that pic looks like an unmade bed where pillows were added for no reason.

As usual Patricia Colwell has given great advice! It might take visiting a few stores but you should be able to find a salesperson who can help you replicate the look in your original photo post.

Bedding content is important and price is dependant on quality and content (linen/bamboo blend, bamboo, 100% cotton, etc) and the thread count for sheets. If you aren’t familiar with pros/cons that’s the first step. Then search/compare items individually and to get the look you are after, you’ll need a cover and duvet. I searched brown duvet covers and quickly found this on Wayfair. It’s much easier to compare prices and content on line for this color especially. Suggest Ikea for the duvet, as they carry lots of options.

Sheets: Suggest Marshalls/Home Sense and I have also found good sheets on Amazon, but reviews are important to reference. If open to ivory or white, you’ll find more options/prices in stores and on line.

Cushions/Throw: Search grey textured cushions and dark grey throws on Pinterest and you’ll see all kinds of styles/prices and also try local stores.

Keep in mind to that if you are going for this ‘look’ almost all staged bedding photos have two duvets in the cover.
