The staff was very respectful and handled me very well as a customer. The employee was at the Grand Forks shop from Fargo as a substitute for another employee who was on vacation. However, the same mattress was ultimately $200 less at Ashley, and the adjustable frame was just $900. I just wanted him to price match, but overall they have good quality mattresses and frames, no doubt, but it's expensive for a common middle-class person. Overall, it's 5 stars, keep it up.👍

Needed a mattress, walked in here and got excellent service from Joey. Walked us through the different types of mattresses, had us test them to figure out the technology you like (springs, hybrid, foam, etc) and then tried various mattresses in your specific style. Had great suggestions on what to try based on your feedback from a specific bed. Super friendly and would go back for my next mattress.

As much as I hate shopping, finding our new mattress was a very pleasant experience! Matt was very knowledgeable and explained about the different types of mattresses that were offered. He read our body language and helped us decide on our new Purple mattress 💜 Thank you Matt and thank you Mattress Firm!
