This is supposed to be Helix’s firmest premium mattress. We paid over 2k to get a mattress in a box that literally felt like a sponge - and it was super bouncy. Not firm as advertised. The mattress wouldn’t support the weight of 2 people in it without sinking and making it feel super uncomfortable. Plus, would not recommend the extremely inconvenient return/refund process. Helix makes you get in touch with a partner to coordinate the pickup of the mattress, instead of doing it themselves. It’s a nightmare.
