Thank you, Bill. Good afternoon to everyone on the call. During the past few months, I've enjoyed meeting many of you and look forward to continuing our discussions at the company's upcoming Investor Day in Chicago on May 8. We hope you'll be able to join us. Let me begin my remarks today by thanking our SLEEP NUMBER team for their execution excellence against our customer-focused strategy, which delivered record top and bottom line results and improved the lives of thousands of customers. In the first quarter, we achieved a 36% increase in sales, a record 34% comparable sales growth and a record 15.2% adjusted operating margin. These results further validated our growth formula and demonstrated the progress we've made in raising brand awareness and in driving increased store productivity. We are leveraging our unique ownership of all customer touch points by consistently innovating across marketing, product, distribution and customer experience. While delivering a record first-quarter performance, we also continued to allocate resources to fund longer-term initiatives to further differentiate and build demand for the SLEEP NUMBER brand. Let me provide you with some detail and insight about the strategy that drove our performance in the first quarter and how we will progress these initiatives for second quarter and beyond. The company's integrated growth formula is comprised of 4 key components: one, broadening awareness of the SLEEP NUMBER brand; two, building consideration with our differentiated products; three, advancing exclusive market-based distribution; and four, providing a unique customer-centric brand experience. Our #1 priority is broadening awareness as we accelerate our strategy to ensure everyone will know SLEEP NUMBER and how it will improve their life. To that end, we continue to evolve and invest in our marketing strategy, an optimized approach to media that combines the reach and frequency of national broadcast TV with additional targeted national and local initiatives. This execution is especially effective during significant consumer mattress shopping periods such as the Presidents' Day event. In order to raise awareness and reach our redefined broader target customer, we increased our media spend by 48% over the previous year. This supported additional week of national broad reach TV with improved reach and frequency, resulting in increased traffic over previous quarters. During the quarter, we also increased local media spend as part of our local market development plan, which includes the aggressive growth strategy for large metro markets. While executing our planned increase in media spend, we leveraged overall sales and marketing expenses by 110 basis points, which contributed to operating margin expansion. The second component of our growth formula is building consideration for SLEEP NUMBER with differentiated products. In January, we launched our new memory foam bed, the m7. Utilizing important consumer insights, we combined our proprietary gel infused CoolFit Foam with exclusive SLEEP NUMBER DualAir technology. Our strategy was twofold: to increase traffic by broadening our addressable market and to increase conversion by exceeding customer's expectations with a unique memory foam product that cools, contours and adjusts. Customers and our sleep professionals have responded positively to the introduction of the m7, which resulted in a mix increase of nearly 600 basis points over the prior year memory foam offering. This launch, as well as the launch of the SLEEP NUMBER AirFit Adjustable Pillow in the fourth quarter, are good examples of how differentiated benefit-driven products broaden consideration of the SLEEP NUMBER brand and drive incremental sales. During the quarter, we also relaunched the Classic SLEEP NUMBER Series, unifying the entire line with our new signature brand standard. Our customer responded well to both the closeout and the introduction of the Classic Series, which contributed to company-controlled unit growth of 25% over prior year in the quarter. Third, we continued to advance our exclusive market-based distribution model. In the quarter, we expanded the aggressive growth strategy, a multi-year initiative designed to more than double market share in 13 of our large underdeveloped markets. When we introduced this strategy in 2011, these markets represented approximately 1/3 of the total U.S. mattress sales, but only 24% of SLEEP NUMBER sales. We launched 2 additional markets in January and entered year 2 in 4 markets, which means we have 6 of the 13 markets in development. This aggressive growth strategy continued to exceed expectations in sales, profit and market share growth. The fourth component of our sustainable growth formula is providing unique brand experience. This is best represented by our relationship-based store experience, which focuses on individualized sleep through the SLEEP NUMBER family of products. Our customer continues to respond positively, resulting in record average sales per store of $1.9 million for the trailing 12 months. This positions us to exceed the previously communicated average sales per store of $2 million in 2012. As we move into second quarter, we will apply our growth formula in a similar yet modified manner. Second quarter is our seasonal low period. It's always more challenging because the quarter lacks a robust consumer mattress shopping event. However, we've advanced our learnings both in and outside of these events and have applied the formula accordingly. Our focus remains on executing against our integrated strategy, including marketing, product distribution and customer experience to drive performance in the quarter and the year, while advancing initiatives and investments for our long-term profitable growth. We will continue to broaden awareness for our brand in stores with the proven media initiatives previously discussed. To that end, we plan to invest in media at a similar percent of sales to first quarter. In the second quarter, we will remain focused on increasing consideration with our differentiated products. We are introducing a Sleep Number Silver Edition bed to commemorate our 25 years of innovation and individualized comfort. This special Innovation Series bed is available for a limited time at a great value for our customers. As we have previously communicated, we expect our growth to come from both existing and new stores as we grow to greater than $1.5 billion by the end of 2015. Our approach is to optimize local market development while leveraging our national exclusive distribution. This positions us to achieve higher average sales per store. Over the past 12 months, we've increased average sales by about $500,000 per comp store, adding an incremental $175 million in profitable sales growth. Most mattress retailers would need to add 150 to 180 stores to grow sales by this amount. Driving increased store productivity or same-store comps is an important part of our strategy. We continue to experience positive results from our new store designs, repositions and remodels. In second quarter, we will reposition 7 locations and remodel approximately 25 stores with our new design. In addition, we will add 5 net new stores as we begin to fill in existing markets to further develop local market share. Our new stores continue to perform equal to or greater than company average in the first year, and we remain on track to increase our total store count by 5% to 8% by the end of the year. Clearly, an exciting second half. Lastly, we've increased our investment to support strategies to advance our customers' total experience including customer research, R&D, distribution, systems and infrastructure. In closing, we have made significant advancements in the SLEEP NUMBER brand experience, resulting in sequential growth in sales, profit and earnings during the past 3 years. Yet we are early in our growth journey, with less than 2% of the unit market share in the industry. This is an exciting time for the company. We have the growth formula in place that leverages our competitive advantages for the benefit of our customers. We have the resources and financial flexibility to continue to invest behind our formula, and we have a talented, experienced, mission-driven team to advance our strategies. For these reasons, we have confidence in our ability to achieve our short and long-term goals and realize the full potential of the SLEEP NUMBER brand. Thank you, and now Wendy will share the details of our financials and 2012 outlook.
