The results
Thought I would add the instructions of how it was made in case anyone wanted to make one. In brackets next to each item is the type I used.
Materials
1 x Wooden Board (4ft x 2ft x 1 inch plywood)
1 x Foam Layer to cover (4ft+10mm x 2ft+10mm x 2 inch blue cushion foam)
1 x Material to cover (2m brown pleather)
5 x Anchor points (50mm x 50mm Ring on plate)
20 x 20mm screws
Tools
1 x Staple gun
1 x Drill
1 x Screw driver
1 x Impact glue
1x Needle and thick thread.
Instructions
1. Mark on the board where you want the ring and plates to go around the edge, ensure the area is 20mm larger than the size of the plate. In my case that was a 70mm x 70mm area. I decided to go for both sides at the mid point and bottom and a single on in the centre of the top.
2. Do the same markings on the foam. Take into account the fact that the foam is slightly larger. This generally means the the area being marked will be set slightly off the edge, in my case it was 5mm on each side.
3. Cut out the areas you marked on the foam. The excesses at the sections at the edges of these areas can also be removed. You should be removing the excess (the 5mm mentioned earlier) from around these areas.
4. Use you impact glue to stick the foam to the board. Impact glue should be used in a well ventilated area. Coat the foam, then the board and once they tacking press them together. Be careful as this stuff is strong and will stick new instantly. I recommend finding someone to help you lower it into position so you can line it up correctly. Also you ensure a proper bond apply pressure to the foam and board.
5. Cut out the required shapes of the material you are using. When doing this remember to add a seem allowance for yourself. You need to cute out shapes for the top of the foam, so in my case this was 2ft x 4ft minus the areas you removed. Then you need to cut out each flat side. Any flat side that would reach the floor should have an extra 3 inches that can be wrapped under the board later. Unfortunately I can not give precise patterns for this as it depends on the number of anchor points you want, also I made the pattern straight on the material so I don't have anything I can show.
6. Stitch it all together. Using needle and thread stitch all the pieces together but leaving the bottom edges alone. This may take a while, I did it by hand and it is the part that took the majority of the time. Once done you should have a cover that can be slid over the board and foam.
7. Slide the material over the board and foam. Flip it to see the bottom. Now pull the excesses from the edges in toward the centre so they don't feel loose but not too tight and begin stapling in in place. IF you are unsure you can look up and upholstering tutorial online.
8. Time to add the anchor points. If you have an electric drill this will be easier, if not a drill and a screw driver will also work. Position the ring and plates in the centre of the areas that you have cut out and screw them in place. I used the drill to make a hole about the right depth and about half of the screws diameter to allow me to easily use a manual screwdriver to add the screws but still have everything secure.
9. Enjoy the results.
