You don't need to justify buying this, at less than a fiver and just the right size to take a glass of wine and a bottle of beer, try and justify not having one in your camping kit. With the leg snapped into the holders on the back of the table top for storage it barely takes up more room than the August edition of the camping magazine. Pull the metal leg out, join the two pieces together and push it in the ground, Drop the table on top of the metal leg and into the retaining hole and eh, 10 seconds later you have the perfect drinks table between your loungers to watch the evening sun go down. The metal leg is quite solid and won't ben or brake easy and the plastic table top seems firm fit for the job.
It takes a few seconds to pull it up, and relocate it anywhere you move your chair to. The anti-slip mat is surprisingly good and grips the drink on quite an angle.
Simple and well made, its a no brainer.
