A mattress includes a top face, a bottom face, a pair of opposing sides defining a mattress width there between, a first microcoil support foam layer and a second microcoil support foam layer. The first microcoil support foam layer includes a plurality of first pockets and a plurality of first protrusions, and the second microcoil support foam layer includes a plurality of second pockets and a plurality of second protrusions. A plurality of separate microcoil cells are formed as lines of microcoils having a width of a single microcoil and a length containing sufficient number of microcoils such that the line of microcoils spans the mattress width. Each one of the microcoil cells is disposed between a given second protrusion and first pocket or a given first protrusion and second pocket.

A mattress has a perimeter rail having a head end, a foot end, and two sides, each having an inner surface, and at least two substantially parallel rectilinear sections. Each section comprises an array of springs whose tension is selected to provide a predetermined firmness for that section. Each adjacent pair of sections is urged into a spaced-apart relationship by a spacing means, where each spacing means comprises a flexible spacer. The flexible spacer restricts or substantially eliminates the translation of movements between the sections of the mattress, while avoiding the use of uncomfortable separation means.

Mattresses are stacked, with support surfaces being substantially in contact, to produce a mattress stack (201). A press (501) applies pressure in the direction of said mattress stack, such that said pressure is normal to the support surfaces and consistent with pressure applied by a reclining body, thereby resulting in reversible compression to form a compressed mattress stack. Restraining elements (601) restrains the mattress stack and the process may be repeated to increase the size of the stack.

This disclosure describes, among other things, techniques for waking a user by changing the user's sleep environment. In one example, a method includes receiving, at a central controller of an air mattress system, at least one user alarm setting, generating, via the central controller, at least one instruction based on the received user alarm setting, and transmitting, from the central controller, the at least one instruction to a first component of the air mattress system to adjust a feature of the first component.

A sofa bed includes: a plurality of elastic modules; a body frame having slide rails arranged thereon; and armrest frames disposed at two sides of the body frame along a longitudinal direction of the body frame, respectively. The slide rails on the body frame are configured to enable the plurality of elastic modules to be mounted on the body frame from an outside of the body frame and to slide thereon to predetermined mounting positions, such that the body frame at one side facing the user is provided with the plurality of elastic modules. The angle between the seat and the backrest portion can be locked for improved operation. The elastic modules, which can be easily installed and uninstalled, can improve the comfort of the sofa bed.
