The combination of individually wrapped pocket springs and zoned foam creates clear lumbar and hip support while the Euro Top adds pressure relief for back and side sleepers. Setup is straightforward and the mattress is fiberglass free, so it appeals to households with sensitive skin concerns and those seeking safer materials for children and pregnant partners.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 in profile:\u003c\/strong\u003e a medium-firm height that fits most platforms and adjustable bases while keeping a low profile for rooms with low bed frames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndividually wrapped coils:\u003c\/strong\u003e hundreds of pocket springs contour to the body for balanced support and reduced motion transfer between partners.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eErgonomic zoning:\u003c\/strong\u003e softer shoulder and hip zones with reinforced lumbar coils help keep the spine aligned and relieve pressure where it matters most.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced edge support:\u003c\/strong\u003e reinforced 2.1-2.3 mm perimeter coils expand usable sleep surface and limit roll-off for people who sleep near the edge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreathable, hypoallergenic cover:\u003c\/strong\u003e an organic cotton cover plus gel-infused foam and open coil structure improve airflow to help sleepers stay cool and dry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiberglass-free and certified:\u003c\/strong\u003e certified CertiPUR-US and OEKO-TEX materials with no fiberglass offer safer sleep for allergy-prone users and families.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis mattress is a good choice for couples who need motion isolation but still want the responsiveness of springs, and for back or side sleepers who benefit from targeted lumbar support.
