Two full coil units of double-tempered recycled steel, wound in our own facility rather than bought from a supplier, which is why both units run uniform 14-gauge instead of whatever a catalog offers. Every spring sits in its own pocket, in both layers — no helical wire threading the coils together, no interconnected grid anywhere in the mattress. Uniform gauge throughout means the perimeter is as firm as the center, with no soft edges. Pair it with our Heavy Duty Foundation, rated to 2,000 lbs of total load.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions \u0026amp; Weights\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eAvocado Green Extra Firm Organic Mattress:\u003c\/em\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTwin: 75\" x 38\" x 10\" — 83 lbs.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eXL Twin: 80\" x 38\" x 10\" — 85 lbs.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFull: 75\" x 54\" x 10\" — 128 lbs.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eQueen: 80\" x 60\" x 10\" — 141 lbs.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eKing: 80\" x 76\" x 10\" — 182 lbs.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCalifornia King: 84\" x 72\" x 10\" — 187 lbs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eMattress ships and delivers flat.
