Silicon Valley has always been recognized for offering those quirky benefits. Nap pods, game rooms, free lunch, transportation--if it's off-the-wall and great, it probably exists. 

More than half (57 percent) of the surveyed workers say they factor in the company's benefits before accepting a job offer, according to recent data from Glassdoor, released on Wednesday. Through its "benefits reviews" feature, the employer reviews platform tabulated responses from hundreds of thousands of users (since August 2014) to rank the top 20 companies for worker benefits. 

Data showed that healthcare, vacation, performance bonuses, and a solid 401(k) or pension plan were the most valued benefits, and that four out of five workers would even prefer those benefits to a pay raise.

It's worth noting that the number of reviews varied greatly on the platform, depending on the size of the company; Glassdoor focused on picking out the most unique benefits, and ranked companies in no particular order. 

From an entire year of parental leave to health care plans that cover gender reassignment surgery, here are the companies with the coolest corporate benefits: 

1. Netflix

The Los Gatos, Calif.-based TV streaming company received an overall benefits rating of 3.7 out of 5, according to 93 reviews on the platform. Netflix offers up to one year of paid leave for new mothers and fathers, who can return part-time or full-time throughout that year, and take time off as needed.

2. REI

More than 180 workers ranked the benefits at REI, the sportswear brand based in Kent, Wash., giving it an overall rating of 4. In keeping with its target demographic, REI offers employees two "Yay Days," or paid days off, to engage in outdoor activities.

Benefits at REI don't kick for temporary workers or interns, however, until they graduate to full time employment.

3. Salesforce

The New York City-based software giant received 543 reviews for an overall rating of 4.5. Employees at Salesforce get six days of paid volunteer time off during the year, and up to $1,000 to donate to a charity of their choice. 

4. Spotify

The music streaming giant might be the only high-profile tech company to cover the costs associated with egg freezing, or fertility assistance. Spotify also offers six months of paid maternity/paternity leave, plus a month of flexible work options for returning parents.

It has an overall benefits rating of 4.2 on Glassdoor, though it's worth noting that to date, only 36 workers have reviewed the company on the platform.

5. World Wildlife Fund

The Washington, D.C.-based non-profit received an overall benefits rating of 4.5, out of 43 reviews. At World Wildlife Fund, employees are gifted with "Panda Fridays," where they can take every other Friday off.

6. Airbnb

The peer-to-peer lodgings company (a former Inc. Company of the Year, and Glassdoor's Best Place to Work in 2016) allows employees an annual stipend of $2,000 to travel anywhere in the world, provided they stay at an Airbnb listing. The tech giant has a rating of 4.6 on Glassdoor, according to 100 reviews.

7. PwC

With student loan debt in the U.S. weighing in at $1.3 trillion, it's no surprise that workers are loving PwC's $1,200 student loan debt reimbursement feature. The New York City-based consulting firm comes has an overall rating of 4.0, according to more than 1,800 reviews on the site.

8. Pinterest

The social scrapbooking site (which made headlines last month when it hired its first-ever Chief Diversity Officer, Candice Morgan) also carries one of the most loved employee benefits programs. It has a unique parental leave policy: Workers get up to three months of paid time off, an additional month of part-time hours, and two counseling sessions. 

Still, the company only has 23 ratings on Glassdoor, with many noting that Pinterest does not match an employee's 401(k) contributions.

9. Burton

The Burlington, Vt.-based snowboard manufacturer offers its workers ski passes and snow days. It has only 12 reviews on Glassdoor, for an overall benefits rating of 4.0.

10. Twilio

The Silicon Valley software company offers benefits including free meals, a Kindle, and $30 each month to spend on books. It has 37 reviews on Glassdoor, for an overall rating of 4.0.

11. Twitter

The social media giant gives workers three free meals a day, on-site acupuncture, and improv classes. It received an overall rating of 4.3, according to 133 reviews.

12. Accenture

The IT outsourcing giant, which has more than 3,8000 benefits reviews, for an overall rating of 4.0. As part of its commitment to promoting LGBTQ rights, Accenture covers all costs associated with a worker's gender reassignment surgery.

13. Walt Disney Company

Employee perks include discounts on hotels and merchandise, as well as free entrance to theme parks. The company has an overall rating of 4.0, according to 428 reviews.

14. Facebook

What's better than a generous parental leave policy? Possibly $4,000 dollars in "Baby Cash," for employees with an infant. The social media has an overall rating of 4.7, according to 383 reviews.

15. Evernote

Glassdoor users are bullish on Evernote's benefits program, giving it an overall rating of 4.3. The note-taking startup offers classes to workers through "Evernote Academy," including on how to bake macaroons. 

16. Epic Systems Corporation

This Verona, Wis.-based software company lets employees take a paid, four-week sabbatical after they've put in five years. It received an overall benefits rating of 4.3, according to 329 reviews.

17. Adobe

The software giant shuts down for one week in December, and another week over the summer. It has an overall rating of 4.6. 

18. Asana

At the San Francisco, Calif.-based IT company, employees are compensated for seeing a life coach. The company has a rating of 4.9 on Glassdoor, though it's worth noting that only nine users have reviewed Asana's benefits program so far. 

19. Zillow

The real estate platform has at least one unique perk: Traveling employees can ship their breast milk. It has a rating of 4.5 on Glassdoor, according to 119 reviews.
