Champion Sports M155 Full-Size Double First Base

Champion Sports M155 Official Double First Base for Safer First

The Champion Sports M155 is an official-size foam-filled double first base built to avoid collisions between the runner and first baseman. The foam fill is soft on impact, and three nylon web straps with three steel spikes lock the base in place. The double width gives each player separate landing space on a baseball and softball diamond, alongside an anchored line like the M250 set.

At 30in it is the official double-wide first base; the strap-and-spike hold means it stakes down without permanent anchors.

Foam Filled, Soft on Impact

The M155 fills an official-size double base with foam, so contact at first is softer than a rigid base, and the double width separates the runner and first baseman. Three nylon web straps and three steel spikes stake it firmly without permanent anchors, which sets it apart from the anchor-seated breakaway double first base. It is the portable, stake-down route to a safer first base.

Staking Out the M155

Set the three steel spikes at first and cinch the three web straps for a firm hold. The foam fill softens contact and the base lifts out for storage. Nothing is permanently installed, so it moves with a portable infield such as the M250 comparison or a foam base set. For an anchored breakaway first base instead, use the M950.

Where It Fits by Field Type

Equipping a Safer First Base

For a youth coach or league, the M155 brings a soft, collision-avoiding first base that stakes down anywhere. It needs no field modification, so it suits shared fields. Compare double-first-base options across the bases and home plates range.

Buyer and Field Workflow

Set the three spikes at first, cinch the three straps, and play. Pull the hardware and lift the base for storage afterward. Keep spare base spikes and a base strap on hand, and pair with an anchored M250 set for the other bags.

Who Buys This Base and Why

Youth leagues, schools, and camps buy the M155 to make first base safer with a soft, foam-filled double base that stakes down without anchors. It separates the players and softens contact.

A portable program that wants safer first-base play without installing anchors is the clearest case, since the M155 stakes down with straps and spikes.

Choosing This Style vs Companions

Expert Recommendation

Choose the M155 for a soft, portable, collision-avoiding first base. For a younger field use the M144, for an anchored release the M950, and build the rest of the infield on the anchored M250 or welded M501.

Alternatives and Companion Styles

Companions: the M144 youth double base, the breakaway M950, the anchored M250 and welded M501 sets, plus base spikes and a base strap for replacements.

What Sets the M155 Apart

Its value is a soft, portable safer first base: an official-size foam-filled double base that avoids collisions and stakes down with three straps and three spikes, no anchors required.
