Sorry for not having a lot of detailed pictures.
Step 1: Gather and Cut Pipe
Depending on the size or your pet, you may have to modify to a larger size or add an additional brace in the middle using a "T" joint.
3/4" pvc pipe - length will vary depending on the measurement you take for your pet. I just bought two full length pipes 6' long.
Cut two pieces 26 1/2" long
Cut two pieces 19 1/2" long
1/2" pvc pipe - 24" long
Cut 4 pieces 6" each.
4 - corner joints 3/4" with 1/2" threaded female
4 - 1/2" male threaded slip caps
4 - 1/2" slip end caps
I did not use any adhesive to join the pipe together since it was a very snug fit.
Step 2: Assemble
1 - I slid the 26 1/2" pipes through the sides of the mesh fabric from our broken patio chairs. You may also use fabric of your choice and sew side strips to allow pipe to slip through.
2 - Then assembled the corner pvc joints to the 19 1/2" pipes.
3 - Slid the 19 1/2" pipes with the corner pvc joints attached onto the 26 1/2" pipes.
4 - Screw male threaded caps to corner joints.
5 - Insert 6" 1/2" pipe for legs.
Step 3: Cap the Leg
The corner joints that are threaded are a good idea to use since you can adjust legs for any uneven floors.
You can also purchase a swim noodle from the dollar store or a foam pipe insulator (from hardware store) and place over the pipes since Buddy did not like laying his chin and head on the hard pipe.
Dogs like to feel air underneath them to stay cool. Using a mesh breathable fabric is great way to accomplish this.
I'd like to hear suggestions on maybe adding a solar powered mini fan underneath the bed to aid in the cooling process to keep my Buddy cool or maybe something cool circulating through the pipes?
