A bed sheet retention system (or kit) 1000 comprising:

• (I) one or more corner brackets 10, wherein each corner bracket 10 comprises:
• (a) a horizontally-extending bracket component 11 sized and designed to extend between a bottom surface 51 of a mattress 50 and a support surface 60 under the bottom surface 51;
• and
• (b) one or more sheet-engaging channels 12 connected to said horizontally-extending bracket component 11 with each sheet-engaging channel 12 comprising (i) two sheet-locking members 13a/13b extending along an outer surface 16 of each corner bracket 10, and (ii) an open guided section 14 extending around a corner 15 of the corner bracket 10 and between the two sheet-locking members 13a/13b;
• wherein each sheet-engaging channel 12 extends substantially within a plane P parallel with said horizontally-extending bracket component 11, and
• wherein each of said two sheet-locking members 13a/13b comprises (i) an upper sheet-locking channel member 13U, and (ii) a lower sheet-locking channel member 13L positioned below and spaced from said upper sheet-locking channel member 13U, wherein each of said upper sheet-locking channel member 13U and said lower sheet-locking channel member 13L are designed to engage with one or more sheet locking strips 30;
• and
• (II) one or more sheet locking strips 30, each sheet locking strip 30 being sized and designed to engage with and extend from (i) said upper sheet-locking channel member 13U to (ii) said lower sheet-locking channel member 13L of each bracket 10/40.

A bed sheet retention system (or kit) 1000 comprising:

• (I) one or more brackets 10/40, wherein each bracket 10/40 comprises:
• (a) a horizontally-extending bracket component 11 sized and designed to extend between a bottom surface 51 of a mattress 50 and a support surface 60 under the bottom surface 51;
• and
• (b) one or more sheet-engaging channels 12 connected to said horizontally-extending bracket component 11,
• wherein each sheet-engaging channel 12 (1) comprises a sheet-locking member 13 extending along an outer surface 16/46 of each bracket 10/40, and (2) extends substantially within a plane P parallel with said horizontally-extending bracket component 11, and
• wherein each of said one or more sheet-locking members 13 comprises (i) an upper sheet-locking channel member 13U, and (ii) a lower sheet-locking channel member 13L positioned below and spaced from said upper sheet-locking channel member 13U, wherein each of said upper sheet-locking channel member 13U and said lower sheet-locking channel member 13L are designed to engage with one or more sheet locking strips 30;
• and
• (II) one or more sheet locking strips 30, each sheet locking strip 30 being sized and designed to engage with and extend from (i) said upper sheet-locking channel member 13U to (ii) said lower sheet-locking channel member 13L of each bracket 10/40;
• and
• (III) one or more attachable accessories 300, wherein each attachable accessory 300 comprises:
• (a) at least one accessory connecting member 301, and (b) an accessory body 302 connected to and extending from the at least one accessory connecting member 301, wherein the at least one accessory connecting member 301 is configured (i.e., designed) to extend within and connect to one or more sheet-engaging channels 12 of the one or more brackets 10/40 so as to position at least a portion of said accessory body 302 (i) above the one or more sheet-engaging channels 12, and/or (ii) below the one or more sheet-engaging channels 12, and/or (iii) within plane P.
