I would gladly rate Affordable Bedding even higher if I could! They carry a NC brand, Kingsdown, which we love! Patrick is so very knowledgeable about mattress construction which helped us make a very informed decision! Delivery has been at our convenience & his delivery team brought the mattresses in and put on the mattress protectors that we were also able to purchase there! Great experience all the way around!!!

I am so glad to have found Affordable Bedding! In my initial search for a great mattress, my focus was on mainstream, commercial stores. Little did I know a locally-owned store would be just what I needed. I came back for a third visit with my husband before making a purchase, and each visit to the store was a great experience -- there was no pressure to buy! Patrick is very knowledgeable and provided details on each mattress we tried. He helped make smooth a process that can be difficult... for many of us finding the right mattress can be a challenge. We chose a Kingsdown mattress -- it is of great quality and the price simply cannot be beat!

What a pleasure purchasing a mattress was! Patrick was so patient in listening to my needs. He took the time to educate me on my options. There was no pressure at all. To my delight Patrick was able to deliver it on the same day. His delivery guys were just as polite and arrived within the timeframe given. I would certainly recommend Affordable Bedding.

We ordered a bed on Wednesday and had it delivered on Thursday all the way down in Spartanburg. Hard to argue with that. And the guys that delivered and set it up were very prompt and professional. And this bed was much less expensive than all the ads I was getting on Facebook and seems to be excelent quality so far. Great service and the fact that Pat sent me homemade cookies had no influence on this review!

We needed a bed for my elderly mother and thought of Affordable Bedding since we’d purchased our own bed there. Patrick showed us our choices and pick something in our budget. And delivery was exceptional. Thank you Patrick for another great experience!
