Pieces you need:

 2 large rectangles

 2 arches

2 triangles 

2 arm-rests

2 semi-circles

1 play mat

Steps:

✔️ Step 1: Place the semi-circles in their arches and place down on the ground on the long thin sides parallel to each other about two feet apart.

✔️ Step 2: Place the two triangles in towards each other to form a single rectangle block and lay it down on the ground in between the two walls just created with each end of the triangle shape touching one of the walls.

✔️ Step 3: Place the  two small rectangles beside the triangles on the ground inside the two semi-circle/arch walls to complete the base.

✔️ Step 4: Option 1. Place one large rectangle flat as a step into the build or on an angle to climb into the build.

✔️ Step 5:  Place the playmat on top of the build in an upside-down V formation with each side being supported by the walls created out of the arch/semi-circles.

✔️ Optional: If you have a wood wobble board, use that as a slide out of the build.
