  1. Cass

    Serta has comfortable mattresses as I have purchased a serta mattress before and I am also happy with this one.

  2. Jason H

    Purchased for my daughter and she loves it

  3. Vanessa

    It has a slight cushy feel on your body but is still supportive for your back and is still comfortable sleeping on your side. Great value for the price.

  4. Viktor

    The mattress is fantastic and huge praise to the delivery guys who managed to get it down to my basement through a very tight staircase.

  5. Rachel

    The delivery service was excellent and the mattress has been great so far. It has not been long but so far I am delighted with everything. Will review further later on.

  6. Sam S

    I don’t know if it is just me but I was expecting the mattress to be more like a medium soft but it feels very soft

  7. Saideh

    The mattress is comfortable and the delivery guys were very helpful

  8. Chris

    The purchase was made easy and our new mattress arrived quickly. The set up was easy and we’ve been enjoying the sleep on our mattress without restless sleep. Thank you

  9. Aysha

    I can’t fault the service at all, but the mattress is disappointing.

  10. Karla

    The mattress is working just fine. If I had the choice I would have chosen a slightly softer mattress but other than that it suits me just fine

  11. Cedric B

    We use this mattress in our guest room and although I have not slept on it myself, our guests seem to really like it.

  12. Ufuk

    To be honest we didn’t like this mattress so much but I am giving the full 5 stars because they allowed us to exchange for something that is better for us and it was cheaper.

  13. Benjamin L

    The mattress is a good quality and the delivery team was very helpful so thank you. One little complaint is I was promised 3-5 business days but it took longer and I had made plans!

  14. William O

    Purchased this mattress with the help of Baris in the store but we didn’t need the mattress for a while because we hadn’t moved into our new home yet. Baris helped us arrange for a delivery date 3 weeks away and then had it delivered exactly on the day that we needed it. We are very happy with the mattress and also the service.

  15. Williams

    This mattress was too sot and not comfortable. Returned without hassle and I appreciate that.

  16. Yaren

    I am so happy with my mattress and also the service provided from start to finish.
