In this page, I will show the algorithms I chose for the 4 cases of the Pattern 4.
I call this pattern “bed”.
No. 153: UFR and UBR look at a side
https://www.speedcubedb.com/a/3×3/VLSUFUL/VLS_153
Algorithm: U2 (r U r’) U2 (R U’ R’) (M’ U M)

No. 155: UFR looks at a side
https://www.speedcubedb.com/a/3×3/VLSUFUL/VLS_155
Algorithm: S F’ (L’ U’ L) F S’

No. 152: UBL looks at a side
https://www.speedcubedb.com/a/3×3/VLSUFUL/VLS_152
Algorithm: (U R U’ R’)2 U’ (R’ F R F’)

No. 154: None of the CP looks at a side
https://www.speedcubedb.com/a/3×3/VLSUFUL/VLS_154
Algorithm: (l’ U’ L U’ L’ U2 l) U (F R’ F’ R)
This begins with left-hand Sune with l’/l, and ends with a so-called Invert Sledgehammer.
Finger trick for Invert Sledgehammer: F by right thumb, F’ by left index finger.
