WASHINGTON (AP) _ Five more manufacturers of a type of infant pillow linked to the suffocation deaths of 19 children joined a nationwide recall of the items Monday, the Consumer Product Safety Commission announced.

The recalls expand the number of recalled pillows to nearly one million. They came 11 days after the agency announced voluntary recalls by eight other manufacturers and retailers involving 644,000 of the ''bean bag'' style fabric-covered cushions sold under several brand names. The cushions are filled with polystyrene pellets.

The latest recall included Comfort Products of Dallas, which commission officials said had resisted the initial recall.

Jacqueline Jones-Smith, CPSC chairwoman, said 19 infants 3 months old or younger had been ''found dead lying stomach-down'' on the cushions since September 1987. The latest three deaths were last January and February, she said. Ten occurred last year.

The soft pillows conform to the baby's shape and could engulf a child placed face down on them, the CPSC said.

On March 6, the commission issued a warning urging parents to discontinue use of the pillows, but it did not move to ban the pillows because such action can take longer than voluntary recalls, said CPSC spokesman Dan Rumelt.

The commission said consumers should immediately stop using the products and contact the manufacturer for any exchange that might be available.

The new batch of recalls and the manufacturers included:

-''Comfort Tote,'' ''Comfy Tote'' and ''Cushie Comfort'' by Comfort Products; 133,800 have been sold.

-''Baby's Cloud'' by U.S. Mom's of Las Vegas; the CPSC says these products should be destroyed because the manufacturer is out of business; about 3,500 were sold between 1985 and 1988.

-''Sof-Sak'' by MFP of Hays, Kan.; 76,000 were sold nationwide from 1986 through February 1990.

-''Comfort Cushion'' by Tailored Baby, Inc., San Fernando, Calif.; approximately 78,000 were sold from 1988 through April 1990.

-''Baby Jacks Bean Bag'' by Jumping-Jacks Shoes, Inc., Monett, Mo., which manufactured about 45,000 sold in Jumping-Jacks Shoes and other retail stores from 1985 through February 1990.

The previously announced recalls were ''Mother's Helper'' by Hollander Home Fashions of Newark, N.J., which announced its recall in January; ''Gold Bug Support Sacks'' by Gold, Inc., of Denver; ''Cozy Cushions'' by Pinky Baby Products of Houston; ''Cozy Baby'' by Cozy Baby Products, Mount Vernon, N.Y.; ''Baby Minder'' by The Fourth Little Pig of San Anselmo, Calif; ''Baby Sak'' by Baby Sak of Pembroke Pines, Fla., and cushions sold by J.C. Penney Co. and the Army and Air Force Exchange Service.

The government's consumer affairs hotline, 1-800-638-2772, provides automated information on individual recalls and takes reports on incidents involving the cushions.
