Raised beds

I am looking at creating some raised beds, height is important to me, about 3ft, I looked into railways sleepers but for the size I need these are looking expensive, what are my other options? I will need something that looks good and can withhold the weight of the soil needed.

The alternatives are brick walls or breeze block walls which require foundations, material and labour so weigh up the various costs and you'll find railway sleepers come out not so expensive.
May I ask why 3'? For sitting on the wall to work the beds or to get access from a wheelchair something lower would be far more comfortable. Knee height works well and would need fewer sleepers as well as less soil.
I used decking planks and 50x50mm vertical stakes about every 80cm of length. This is strong enough and the wood is pre-treated so will last a good few years if also lined on the inside. These are only about 2 feet high though:
There's over 2 cubic metres of topsoil in them, weighing about 2 tonnes.
I am looking at 3ft high for beds and seating.
Paint them with an enamel and clad the top and bottom with timber held in place with either bolts or exterior adhesive.
I have now got four of these and I love them.
These are gravel boards, with concrete posts. Permanent, easy to maintain, and not expensive.
