MEMORANDUM**

California state prisoner Darrel L. Smith appeals pro se the district court’s judgment dismissing his 42 U.S.C. § 1983 action for failure to state a claim pursuant to 28 U.S.C. § 1915A. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review de novo, Resnick v. Hayes, 213 F.3d 443, 447 (9th Cir. 2000), and we affirm.

The district court properly dismissed Smith’s claim that he was deprived of a mattress for 24 hours. See Hernandez v. Denton, 861 F.2d 1421, 1424 (9th Cir. 1988), vacated on other grounds and remanded (24 hour deprivation of mattress does not *78rise to the level of a constitutional violation).

We do not consider claims two, three, and four from Smith’s opening brief because those claims are the subject of separate actions in the district court.

AFFIRMED.
