We have had a sleep number bed for 25 years and it was time to upgrade. We went to the Copaigue store and everyone was very helpful in educating us on what the new beds had to offer. We took advantage of a great sale and bought a new bed and pillows. Installation was seamless and neat. The installer helped load the app and informed us of its benefits. The app is great to understand our sleep patterns. We are very happy with with our purchase. Hope it will last for the next 25 years!

I purchased the newest Comfort Mode full size mattress and I am happy to say I am very pleased...took a little getting accustomed to but I am happy to say I no longer need visits to my chiropractor..I have also purchased a Down alternative curved pillow and I am looking forward to using that tonight... My salesperson Bukhari at your Copiague store was very knowledgeable and understanding my needs in explaining all the aspects of your merchandise. Again, thank you to Bukhari I would recommend sleep number beds to my friends. Thank you and have a good day..

Stopped by the store yesterday. Damion was so helpful and patient!! I had 100 questions about the beds etc and he dedicated time to help answer professionally & with such a friendly energy too. We will absolutely be back to purchase once we figure out exactly what we want. I recommend swinging by the store if you’re curious about these mattresses like we were. Damion never once tried to push a sale or put pressure on us.

We had a great experience at the Copiague location. Damion and Bukhari were both very helpful in showing us how the bed worked and providing us a demonstration. They were friendly and informative and helped us select pillows and bedding as well. Our bed arrived yesterday and we couldn’t be happier with the product.
