"Deep summer is when laziness finds respectability," author Sam Keen once quipped.

But if your vacations have not quite been approved yet -- and your day at the beach is just a daydream as you put in hard hours at the office -- you might consider a "sunny" smartphone case to lift your spirits. To make your choice easier, we have compiled some of our seasonal favorites:

  • What could be more calming than the thought of a lawnchair on a deserted beach -- complete with white sand, turquoise water and a palmtree to shield you from the Caribbean sun? That destination of your dreams is pictured on Palm Tree and Beach Chair 2 Barely There case, which is available for the standard iPhone, the iPhone 6 Plus, as well as a number of other smartphone models. The form-fitting, featherlight cover is made from impact-resistant hard plastic, printed right here in the United States and will set you back between $42.95 (standard) and $47.95 (Plus).

  • Looking for something a little more artistic? Then you might like the Beach Painting/Deck Chairs case from Fine Art America, which features a colorful, beach-inspired oil painting by Australian impressionist artist Jan Matson. This slim-profile cover, too, is impact-resistant and comes with the maker's money-back guarantee. It is available for both the standard iPhone 6 and the iPhone 6 Plus and costs $35 irrespective of the model.

  • Are you among the lucky ones who are actually headed to a real beach? Then you need to take a look at BessmateTM 2 Waterproof Protection case sold on Amazon.com. This innovative cover, which allows you to submerse your smartphone more than 6 feet deep, will make sure that your favorite device returns unscathed once your vacation is over. (You are even set for your next ski trip because the case is snowproof, as well!) And for just $19.99, it comes with an anti-reflective optical glass lens for the high-quality photos you might want to take on your trip.
