    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
