CSS Question

How do I make this layout with flexbox?

I've got a form with a couple areas to it and I've been trying to figure out how to get flexbox to lay something out like this:

Desired Design

If possible, how could I do this while using the least amount of parent containers? (Or, why might I not want to do that?)

Stumped enough by not having achieved this that I think asking is the right move. Still wrapping my head around it all.

.wrapper {
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;  
  -webkit-flex-flow: row wrap;
  flex-flow: row wrap;
  font-weight: bold;
  text-align: center;

.wrapper > * {
  padding: 10px;
  flex: 1 100%;

.header {
  background: tomato;

.footer {
  background: lightgreen;

.main {
  text-align: left;
  background: deepskyblue;

.aside-1 {
  background: gold;

.aside-2 {
  background: hotpink;

@media all and (min-width: 600px) {
  .aside { flex: 1 auto; }

@media all and (min-width: 800px) {
  .main    { flex: 3 0px; }
  .aside-1 { order: 1; } 
  .main    { order: 2; }
  .aside-2 { order: 3; }
  .footer  { order: 4; }

body {
  padding: 2em; 
<div class="wrapper">
  <header class="header">Header</header>
  <aside class="aside aside-1">Aside 1</aside>
  <aside class="aside aside-2">Aside 2</aside>
  <footer class="footer">Footer</footer>
