    Just a really comfortable mattress tbh. Glad I made this choice.

  2. Sujin

    I tried a bunch of ‘soft’ mattresses and none of them were actually soft. I can tell everyone with full confidence that this mattress is actually soft! I love it!

    I am a side sleeper and I need something really soft for my hips and this just works perfectly for me! Love it so much!

    I purchased this mattress after using my old mattress for 14-15 years. This is a beautiful mattress, it always stays cool and doesn’t create any pressure points. Will recommend it to everyone.
