I had an amazing experience at 321 Mattress in Gardner, Kansas! From the moment I walked in, the staff was incredibly friendly and helpful, making the whole mattress shopping experience smooth and enjoyable. They have a wide selection of mattresses, and I was able to find the perfect one for my needs. What really stood out to me was the financing options available through Snap Finance. It made the purchase easy, even with budget concerns. With Snap Finance, you can get approved quickly, and the flexible payment plans give peace of mind knowing I could pay over time. It's the perfect option for anyone who needs an affordable way to invest in a quality mattress without the upfront cost! Another fantastic thing is 321 Mattress' partnership with the Special Olympics of Kansas. It’s awesome to see them supporting such an important cause. It’s always great when local businesses like this give back to the community, and knowing that my purchase helps support the Special Olympics makes it feel even better. If you’re in the area or surrounding cities like Overland Park, Olathe, or Shawnee, I highly recommend checking out 321 Mattress. Great service, great products, and financing that works for you! #GardnerKS #SnapFinance #KansasMattress #SpecialOlympics #AffordableFinancing #SupportLocal #OverlandPark #Olathe #Shawnee #MattressShopping #KansasCommunity #SpecialOlympicsOfKansas
View on GoogleKU STUDENT’S DREAM- I was looking for a mattress for my apartment at KU and could not believe it when I found this place. 30 minute drive from Lawrence to save thousands of dollars. I was expecting to get a cheap amazon mattress for the next few years of living in my apartment due to $, but now I have a luxury mattress for the same price. Their business strategy is awesome for both parties and the mattresses are in pristine shape. They have a display room with many options that you can try before buying. Even with the great prices, they offered to help resolve defects if they occur. They offered to drive it to Lawrence for cheaper than a U-Haul would’ve been. Super easy pickup process especially since they are in plastic packaging that ensures waterproofing for transport. Locally, family owned. 5/5. Don’t miss out.
View on GoogleBest Price & best customer service ever! Madison and Edward were very helpful in helping us pick out a mattress and made sure that the mattress was delivered at the most convenient time for us. The delivery people were efficient and knowledgeable as well as polite and friendly. I cannot recommend 321 Mattress enough!
View on GoogleFamily owned, punctual, down to earth, and good prices. Madison and Bryce were incredibly kind and easy to work with. They delivered the mattress in perfect condition, and was kind enough to help unpack it. If you are going to buy a mattress do it here I can not recommend it enough. Also the store dogs are adorable :)
View on GoogleFrom the moment I walked in the store I was treated like family. Madison was absolutely amazing. I was on the hunt for the perfect pillow. Madison suggested a pillow demo. I was able to lay my head on every pillow they had in the store. She was determined to help me find the perfect pillow and did we ever. The Cariloha pillow was just right! A big thank you to the team at 321 mattress for an amazing experience. I’ve never received such a personal shopping experience. Highly recommend. I’ll definitely be back for that amazing mattress that massages and has surround sound. How cool!
