Britax Cypress

Installation: Moderate$$$

Quick verdict

Verdict
Recommended
Evidence
Moderate

Consumer Reports rates its crash protection Better with 4/5 vehicle fit in every method, and found its ClickTight lockoff smoother than the Willow's.

Good
  • Consumer Reports: Better crash protection; vehicle fit 4/5 with LATCH, belt and carrier-only.
  • CR lists excellent labels and instructions and flame-retardant-free fabrics.
Caution
  • CR: the lockoff "can be difficult to close if belts have too much tension".
  • Mid-pack overall score (67, 26th of 46); out of stock at Britax when checked.

What we could not verify

  • Only one lab has tested it.
  • The scope of Britax's flame-retardant claim is unclear.
  • CR fit 4/5 for LATCH, belt and carrier-only; the lockoff needs care. Lockoff operation is awkward to route and can be difficult to close if belts have too much tension Multiple harness loops behind seat may cause confusion during harness adjustment These recorded installation cautions need review against the Recommended rule. A score is kept on its laboratory scale; no new numerical cutoff has been applied.

Why we reached this verdict

The Cypress is Britax's other ClickTight infant seat, and Consumer Reports found its lockoff works "smoothly compared to the Britax Willow infant seat", though the belt needs care to thread and the lockoff can be hard to close if the belt is overtightened. CR rates crash protection Better with 4/5 vehicle fit for LATCH, belt and carrier-only installs, and lists excellent labels and instructions.

Its overall score (67) is mid-pack, and only one lab has tested it. Britax's own flame-retardant statement is attached to the accent fabric, while CR lists flame-retardant-free fabrics as a strength; PFAS is not addressed. It was out of stock at Britax on September 23, 2026.

Evidence at a glance

Independent crash evidenceCR crash protection Better. Evidence grade A-: One independent program crash tested this model, or tests cover the same seat in a different fabric trim.
Installation and misuse resilienceModerate. CR fit 4/5 for LATCH, belt and carrier-only; the lockoff needs care. Good in some methods but weak in one, or the labs disagree, or a design requires re-installation every trip.

Independent crash tests

Consumer Reports and BabyGearLab run their own crash tests with different equipment, methods and scales. Neither publishes raw measurements, so we report each result in the lab's own terms and never combine them. Passing the federal standard is required of every seat and is not a comparative result.

Installation features and lab observations

  • ClickTight belt installation (Britax); CR: operates "smoothly compared to the Britax Willow infant seat" but "requires extra attention to thread the belt properly"
  • ReboundReduce stability bar (Britax)
  • Quick-Push LATCH connectors (Britax)

Features are as described by the manufacturer unless a lab is named. A feature's presence is not evidence of better crash performance on its own.

Federal compliance and recalls

Every seat sold in the US must meet FMVSS 213. The side-impact requirement, FMVSS 213a, applies from December 5, 2026. The manufacturer states: “Side impact tested”. Manufacturer statement; we did not verify certification.

No recall of this seat was located in NHTSA's recall data (searched September 23, 2026).

Check your own seat by its model number and manufacture date at nhtsa.gov/recalls, and register it with the manufacturer so recall notices reach you.

Materials and chemical claims

  • “Double-knit mélange accents... naturally flame-retardant with no added FR chemicals” (Britax, manufacturer statement)

Britax's wording attaches the claim to the accent fabric; CR separately lists "Flame-retardant-free fabrics" as a pro. PFAS is not addressed.

“Free of added flame retardants” means the manufacturer says none were added on purpose. It is not a lab result showing none are present, and no seat on this page has published independent chemical testing.
