We had a great experience with William at Mattress Warehouse. I came with my parents to help them choose a mattress, and William was incredibly knowledgeable, patient, and kind throughout the entire process. He took the time to explain everything clearly and helped us find the perfect fit without any pressure. On top of that, he gave us a fantastic deal on the mattress they purchased. I would highly recommend both William and this location, and we’ll definitely be back to replace our other mattresses in the future!

I just purchased a mattress from William and had a great experience. He was super informative and was able to answer all our questions, even encouraging them. He let us take our time talking and testing beds, trying to choose between two. I can't speak about the mattress yet as I've not received it but I will try to update once I've had it for a minute. ***Update It turned out that we didn't need the brackets we paid $24 for, to attach the the headboard. The delivery people took them away along with our old mattress and we were assured we'd get a credit to our credit card. Over a month later we still haven't gotten the credit although they confirmed receiving them and said numerous times they'd credit us. How is it that my payment was processed immediately but it's this ridiculous ordeal to get the credit? Also the matress feels way firmer than the one in the store. I'm hoping it gets better, but have no confidence in the exchange process that they tout as a benefit of buying from them vs other stores who have you deal with the manufacturer directly.

Rose is fantastic! She helped me pick out the perfect mattress and protective cover to go along with a new box spring. She was so helpful and kind during the process by explaining everything to make sure everything was comfy.

Went to get a new bed. Rose helped us. She was very accommodating to what we wanted. Asked our preferred firmess. Let up try all the ones we wanted and suggest a few that was more to our liking. Very patient. Bought the bed right there. Delivery was smooth. Nice guys. Will buy again.

Will was very helpful and knowledgeable when I was searching for mattresses! He explained everything in ways I could understand and was very patient throughout the process. He took the time to understand my financial situation and helped me to the best of his abilities.
