What about these!!
All you need are two of your 8 feet railway sleepers, a fence post and some decking.
RAILWAY SLEEPERS USED:
New British Pine eco friendly railway sleepers
All credit to you. What a clever and yet deceptively simple design like an armchair made from Lego bricks! Bold, chunky, and clean lines that are as eye-catching as they are comfortable. This railway sleeper armchair could be a classic of the future!
