Mo was such a great help in finding me the perfect mattress (and at an awesome price)! I'm a picky shopper in general, and he had utmost patience and kindness throughout my shopping experience. He is very knowledgable and quickly helped me figure out which options fit me best. I highly recommend Mattress Warehouse, and especially Mo, for your mattress shopping!!

The crew was great; they were accommodating but not overly aggressive. We kinda knew what we wanted and Ernie, Mo and the "Boss" worked to find it. We're sleeping great. I'd recommend shopping at Mattress Warehouse of KOP.

Ernie and the Mattress Warehouse team were just wonderful! We had a very bizarre situation where the original mattress we bought didn’t fit our bed, and he helped us get a replacement at an incredibly fair price! They had a machine that ran a test to determine the perfect mattress for my body type and sleep style, and I couldn’t be more grateful. They even went out of their way to make sure we able to pick up the replacement at a convenient location for us. Great customer service, great experience!

My boyfriend and i purchased our new bed from Ben at Mattress Warehouse about a month ago! Honestly, it turned out to be the best experience. Ben was super thorough in going over all the bed options and making sure we were going to walk out with the right one. He had answers to all of our questions and was really very kind/personable. Before getting our new mattress, i can’t remember the last time i slept straight through the night. I honestly haven’t slept this well in years! Thank you so much, Ben! You have our highest recommendation!!!
