Simmons Kids, a division of The Simmons Manufacturing Co. LLC, is recalling about 20,000 crib mattresses. Some of the crib mattresses can measure smaller than the 271\u20444-inch minimum width requirement for cribs, creating a gap between the mattress and crib side rails, posing an entrapment hazard to infants.

The recalled mattresses involve open coil crib mattresses manufactured from July 1, 2006 to March 23, 2008, with a color label attached to the top or side of the mattress that has the following model names: Pottery Barn Kids by Simmons Kids Lullaby; Simmons Kids Slumber Time Evening Star Luxury Firm; Simmons Kids Baby Mattress Series 400; and Simmons Kids Baby Mattress 234 Coil Count.

The crib mattresses also have a law tag that is sewn into the edge of the mattress. The law tag has the date of manufacture and in most cases will contain one of the following model numbers: H59044.15.0014, M59082.15.0002, M59027.15.0002 or M59065.15.0006.

Pottery Barn Kids and nursery furniture retailers sold the mattresses from July 2006 through May 2008 for between $100 and $150.

Consumers should measure the width of their mattress, placing it on floor and measuring the width near the middle, from the outside edge of the tape binding to the opposite side of the mattress. Consumers should immediately stop using the mattress if it measures less than 271\u20444 inches and contact Simmons Kids to receive a replacement mattress.
