My in-store experiences have been informative and very helpful. I'm over age 70, have back problems, was new to the concepts and features of Sleep Number, and had numerous questions every step of the way. Mikaela helped me with bed selection, setting up delivery for a time that was convenient for us, and by making recommendations for a variety of bedding types. I was impressed by her knowledge, attention to detail, patience, caring, and all-around kindness. About my new bed: I've only used it for one week, but it gets an A+ so far. It took a little time for me to adapt, but I'm getting longer and better sleep already due to much less tossing and turning at night. I can actually look forward to bedtime again!

We went into the Sleep Number Mattress Store to just look around and ended up leaving with a mattress we absolutely love! Mikaela and Kalon were extremely helpful and friendly and we would highly recommend this store and mattress to anyone!

Mikeala did a great job explaining the whole Sleep Number bed operation. We are very happy with our bed buying experience. Although, quite expensive. We've only had the bed for a week, so we are still adjusting to the right numbers for the best Sleep.

Haven't received the new bed yet but we have had a sleep number bed for around 20 years and it has been a great bed. Mikaela was very helpful.
