What 4Sleep customers have to say

  • “After a lot of research, we decided to buy the 4Sleep mattress on line. It was nearly a third of the cost of what my husband was looking at buying. We love our new mattress…great support, very comfortable, don’t feel movement from my husband. I highly recommend the 4Sleep mattress!!” – Anna L.
  • “I was very skeptical and not quite sure but I LOVE my 4sleep bed now. And so does my 10 year, 100+lbs puppy Lucy. She actually frowns when the alarm goes off in the morning because of how comfortable she is. It’s really very comical. My son loves it so much I have to bribe him to sleep in his own bed! So, Thank you for making my puppy, my 7 year old and ME so happy!” – Erin M.
  • “I was sold on the idea that I didn’t have to shop for a mattress, with 4 Sleep. I mean, how well can you even tell by trying one out for 5 minutes? The ordering process was quick and easy. I had a question about my order and I received great customer service! The 24 hour wait to sleep on the mattress was torture but WORTH THE WAIT!!! I fall asleep faster, sleep better throughout the night, and wake up happier! I will recommend this mattress to anyone who will listen!” – Elle H.
