Our first mattress that wasn't second hand and we're thankful we went with Helix! We got the Dusk Luxe w/ GlacioTex Cooling Cover (as I almost always used to sweat through the night) soon after our baby was born. With the new mattress and foundation, the difference in comfort was like night and day - as an added bonus, all the creaking of mattress springs and the old box spring pieces that would often wake our newborn as we tried to groggily sneak back into bed were replaced by sweet, safe silence. Strongly recommend to anyone interested in a comfortable and quiet bed boasting a cooler night's rest!
