Ellen Burns was in the crowd. The Atlanta Braves were playing the New York Mets in Queens in early May, and the game had drawn more than 23,000 fans to Citi Field.

Burns, an administrative assistant at a New York CPA firm, has anxiety and found herself needing a bit of quiet time, so she headed to a newly designated space tucked in a corner near Suite 229 on the Empire level, away from the main concourse, protected from the elements and out of view

Designers of the "sensory nook" say the space was created for guests with special needs, but is free for everyone else. It has an overhead light that shines when it is powered on. A board with stars. If needed, it can vibrate.

Eric Petersen is the director of ticket services for the Mets and chairman of the team's accessibility and Disability Alliance.

People need that at times. Consider a family that has tickets to a game and a child with an illness. After a long trip to the stadium or arena, parking, walking with the growing crowd filing in while waiting for the game to start, the noise inside can get loud. A child may need a break. Without a quiet place, that family might turn around and go home. A sensory space can provide a place and time to relax.

The first sports venue in the US to be certified as sensory inclusive was the home of the NBA's Cleveland Cavaliers. Since then, these kinds of spaces, whether full rooms or booth-like areas, are becoming more commonplace wherever there are spectators.

It is the sixth such space in baseball. The NHL teams had sensory rooms. Nine others have areas that include an outdoor patio space, nursing room, medical room or conference room, and 29 clubs make sensory items like shaded glasses and noise-canceling headphones available. There is a quiet area created by 13 NBA teams. The Baltimore Ravens, which will have five rooms when the season starts in 2022, are one of at least 20 NFL organizations that had full rooms last season.

The M&T Bank Stadium had two installed on the lower level in 2019. The team will have two upper-level spaces ready for the home opener.

All of their rooms are multi-purpose and include space for nursing mothers, with bean bag chairs, couches and a television to watch the game at a desired level of volume. People can control the lighting. The space the Ravens wanted to create was like that. The first preseason game of the Ravens last season was attended by families connected to the Baltimore suburb of Pathfinders for Autism.

There are two nooks in the northeast and northwest entry lobbies of Allegiant Stadium, the home of the Las Vegas Raiders.

Providing relief for people who are left to fend for themselves has been a priority for KultureCity. It helped create many similar spaces, including 200 sensory rooms in five countries. The Mets staff was trained in knowing what to look for.

The sensory room is a place for individuals who might be feeling overwhelmed to relax.

It could be an illness, or it could be the first time back in a large event since the rules were relaxed. They are a bit anxious because of the crowds, lights, mask, and no mask. The rooms are accessible by all ticket-holders, and allow individuals to step away for 10 to 15 minutes.

KultureCity has sensory spaces on cruise ships and in schools. The first step for the Mets is hoped by Srivastava. There are 11 MLB clubs that are sensory certified but don't have a space yet. The past three All-Star Games, the past three postseasons and the 2019 London Series were worked on by KultureCity.

The Oakland A's sensory room was created in partnership with a nonprofit that helps families with children with disabilities. Shawn Stockman is a member of the R&B group Boyz II Men. The Center for Autism and Related Disabilities at the University of South Florida had a consultation with the room of the baseball team. There are more than two examples.

The ultimate goal is to have every stadium and arena have the bags. We can push the boundaries and see if we can have more than one room.

Some people have questioned why guests come if they are not comfortable. She said that they are committed to making sure that inclusion is part of the experience at all venues. There are trained staff in the sensory rooms at all venues. If there are any issues that arise, they are reported up the chain at the venue.

The cost varies from $5,000 to $20,000 depending on location.

The emergency room physician and the physician from the critical care unit founded the company. The couple has experience. Their older son was diagnosed with a disorder.

The company has a board that includes a singer, an actor, a reality star and a basketball Hall of Famer.

Wilkins is a franchise legend with a statue in front of the arena and is a vice president and special advisor to the CEO of the Atlanta Hawks. He remembered taking his daughters to games and having to scramble when they needed some time away from the noise and antics of mascot Harry the Hawk. Wilkins would take his daughter to the family lounge to play video games. It was not a long term solution.

Wilkins said that when her daughter was younger, the family room was where all the kids went. I had to make sure that someone was with her to keep her calm.

Wilkins talked about parents of children with special needs and shared experiences with Maha before he joined KultureCity. They met in person.

Wilkins said that he knew at that time that he was going to be his calling. There is a need for this when there are different episodes. This is a place where they can balance themselves out.

The teams that don't have designated areas have taken steps to make sure games are more inclusive for people with sensory needs. Game-day staffs have been trained to be aware of the needs of guests and have sensory bags and other items available.

A bag provided by KultureCity has a visual thermometer that helps people who don't communicate with one another. If they are feeling distressed in the middle of a packed concourse at an NBA playoff game, they can point to the back of the thermometer as a sign of worry. There is a lanyard that identifies the person who wears it as having a sensory need. It is a good start.

The Mets and KultureCity worked together to make Citi Field a sensory-inclusive venue. The nook was installed three years later. The Mets have an employee resource group that hatched the plan that resulted in the nooks, and they hope to eventually have a larger space.

There are people from that group that have expressed how excited they are for this being.

Wilkins said that a person with a fan might just need a break.

Several people visited the current Citi Field space over the course of the May day when Burns attended. The game was stalemated through the first five frames before the Braves scored seven in the sixth to take a 9-2 victory. It was a routine, early-season game for the first-place Mets, and the inclusion of the sensory nook was a breath of fresh air.

At one point, members of the softball team from New York entered the area. Four of the girls sat together. They relaxed away from the crowd and smiled.

Burns was on one end of the booth and in the hallway. She looked at her phone while wearing a Mets cap and sweatshirt.

When she was asked what she felt, she replied with a sense of calm.
