A orsfeature of the invention resides in a particular construction of the spring sec- 'tions which increases the ease andcomfort' .of coi'led springs, andpermits ready adj st I I ment' of the m'ovable sections. In all prior coiled spring constructions known to me the I upper border frame-is disposed about'thesece.

tion in asingle plane; that is, the upper edges of the spring section are sharp, or square. V g V M w :Sections having such border frames; are unsectionsaare :detachablyi connected to' the bed desirable in beds of this type; because being may'cause undue wear of the mattress.

: sharp theyprojectinto the mattress and'mfay 7 cause di'scomforttotheoccupant of thebedi o Furthermore, the rubblngof sharp'corne'rsh cent ends of successive sections to lie below the top, or border, plane of the section. 'In

as shown at 14, andin the preferred embodimerit, adj acent'ends-"ofi tl'iebord'er' frames c'on= verge downwardly, all as seen in Figs. 1 and 3. This construction has the further advantage that through its use the sections may be ,placed closer together without interference between them when adjusted, and provide a more nearly" continuous spring structure when allthe s'ectionsarehorizontal, than is a possible with prior types of border frame con.- struction. 1,; In the bedseprovided according rent-ion, the: adjustable section or; sections may be raised; lowered". and" held in position by any suitable/means; several of which are known and'rused 'in"v adjustable beds; One

- A further advantage of the bed resides in the feature of replaceability of separate spring sections. @wi-ng to une-i' en-distribuvtion of weight, coiled springs may become impaired insoine sections of the bed before 7 mediate sections ,5, which usually become damaged first, are replaced at will; 7 The pivotal: bolt mounting. of the end sections: makes:-
